Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Amino Acid Sequence
Sequence Homology, Amino Acid
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Sequence Homology, Nucleic Acid
Sequence Analysis, DNA
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Open Reading Frames
DNA Restriction Enzymes
Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another. EC 3.21.1.
Nucleic Acid Hybridization
Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands. (Kendrew, Encyclopedia of Molecular Biology, 1994, p503)
Genetic Complementation Test
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array. (King & Stanfield, A Dictionary of Genetics, 4th ed)
Synthetic or natural oligonucleotides used in hybridization studies in order to identify and study specific nucleic acid fragments, e.g., DNA segments near or within a specific gene locus or gene. The probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the probe include the radioisotope labels 32P and 125I and the chemical label biotin.
In Situ Hybridization
Electrophoresis, Polyacrylamide Gel
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Recombinant Fusion Proteins
A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Gene Expression Regulation
Promoter Regions, Genetic
A process whereby multiple RNA transcripts are generated from a single gene. Alternative splicing involves the splicing together of other possible sets of EXONS during the processing of some, but not all, transcripts of the gene. Thus a particular exon may be connected to any one of several alternative exons to form a mature RNA. The alternative forms of mature MESSENGER RNA produce PROTEIN ISOFORMS in which one part of the isoforms is common while the other parts are different.
Reverse Transcriptase Polymerase Chain Reaction
Gene Expression Regulation, Enzymologic
Species- or subspecies-specific DNA (including COMPLEMENTARY DNA; conserved genes, whole chromosomes, or whole genomes) used in hybridization studies in order to identify microorganisms, to measure DNA-DNA homologies, to group subspecies, etc. The DNA probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the DNA probe include the radioisotope labels 32P and 125I and the chemical label biotin. The use of DNA probes provides a specific, sensitive, rapid, and inexpensive replacement for cell culture techniques for diagnosing infections.
DNA Transposable Elements
Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.
Repetitive Sequences, Nucleic Acid
Sequences of DNA or RNA that occur in multiple copies. There are several types: INTERSPERSED REPETITIVE SEQUENCES are copies of transposable elements (DNA TRANSPOSABLE ELEMENTS or RETROELEMENTS) dispersed throughout the genome. TERMINAL REPEAT SEQUENCES flank both ends of another sequence, for example, the long terminal repeats (LTRs) on RETROVIRUSES. Variations may be direct repeats, those occurring in the same direction, or inverted repeats, those opposite to each other in direction. TANDEM REPEAT SEQUENCES are copies which lie adjacent to each other, direct or inverted (INVERTED REPEAT SEQUENCES).
CELL LINES derived from the CV-1 cell line by transformation with a replication origin defective mutant of SV40 VIRUS, which codes for wild type large T antigen (ANTIGENS, POLYOMAVIRUS TRANSFORMING). They are used for transfection and cloning. (The CV-1 cell line was derived from the kidney of an adult male African green monkey (CERCOPITHECUS AETHIOPS).)
Nuclear Transfer Techniques
Mutagenesis where the mutation is caused by the introduction of foreign DNA sequences into a gene or extragenic sequence. This may occur spontaneously in vivo or be experimentally induced in vivo or in vitro. Proviral DNA insertions into or adjacent to a cellular proto-oncogene can interrupt GENETIC TRANSLATION of the coding sequences or interfere with recognition of regulatory elements and cause unregulated expression of the proto-oncogene resulting in tumor formation.
A theoretical representative nucleotide or amino acid sequence in which each nucleotide or amino acid is the one which occurs most frequently at that site in the different sequences which occur in nature. The phrase also refers to an actual sequence which approximates the theoretical consensus. A known CONSERVED SEQUENCE set is represented by a consensus sequence. Commonly observed supersecondary protein structures (AMINO ACID MOTIFS) are often formed by conserved sequences.
Physical Chromosome Mapping
Mapping of the linear order of genes on a chromosome with units indicating their distances by using methods other than genetic recombination. These methods include nucleotide sequencing, overlapping deletions in polytene chromosomes, and electron micrography of heteroduplex DNA. (From King & Stansfield, A Dictionary of Genetics, 5th ed)
Gene Expression Regulation, Developmental
Gene Expression Regulation, Bacterial
Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
A technique with which an unknown region of a chromosome can be explored. It is generally used to isolate a locus of interest for which no probe is available but that is known to be linked to a gene which has been identified and cloned. A fragment containing a known gene is selected and used as a probe to identify other overlapping fragments which contain the same gene. The nucleotide sequences of these fragments can then be characterized. This process continues for the length of the chromosome.
A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).
Chromosomes, Artificial, Bacterial
A group of genetically identical cells all descended from a single common ancestral cell by mitosis in eukaryotes or by binary fission in prokaryotes. Clone cells also include populations of recombinant DNA molecules all carrying the same inserted sequence. (From King & Stansfield, Dictionary of Genetics, 4th ed)

Protein Sorting Signals
The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).
Chromosomes, Artificial, Yeast
Chromosomes in which fragments of exogenous DNA ranging in length up to several hundred kilobase pairs have been cloned into yeast through ligation to vector sequences. These artificial chromosomes are used extensively in molecular biology for the construction of comprehensive genomic libraries of higher organisms.
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
Deoxyribonucleases, Type II Site-Specific
Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 184.108.40.206.
A subclass of enzymes which includes all dehydrogenases acting on primary and secondary alcohols as well as hemiacetals. They are further classified according to the acceptor which can be NAD+ or NADP+ (subclass 1.1.1), cytochrome (1.1.2), oxygen (1.1.3), quinone (1.1.5), or another acceptor (1.1.99).
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

Novel regulation of the homeotic gene Scr associated with a crustacean leg-to-maxilliped appendage transformation. (1/69323)Homeotic genes are known to be involved in patterning morphological structures along the antero-posterior axis of insects and vertebrates. Because of their important roles in development, changes in the function and expression patterns of homeotic genes may have played a major role in the evolution of different body plans. For example, it has been proposed that during the evolution of several crustacean lineages, changes in the expression patterns of the homeotic genes Ultrabithorax and abdominal-A have played a role in transformation of the anterior thoracic appendages into mouthparts termed maxillipeds. This homeotic-like transformation is recapitulated at the late stages of the direct embryonic development of the crustacean Porcellio scaber (Oniscidea, Isopoda). Interestingly, this morphological change is associated with apparent novelties both in the transcriptional and post-transcriptional regulation of the Porcellio scaber ortholog of the Drosophila homeotic gene, Sex combs reduced (Scr). Specifically, we find that Scr mRNA is present in the second maxillary segment and the first pair of thoracic legs (T1) in early embryos, whereas protein accumulates only in the second maxillae. In later stages, however, high levels of SCR appear in the T1 legs, which correlates temporally with the transformation of these appendages into maxillipeds. Our observations provide further insight into the process of the homeotic leg-to-maxilliped transformation in the evolution of crustaceans and suggest a novel regulatory mechanism for this process in this group of arthropods.

Mrj encodes a DnaJ-related co-chaperone that is essential for murine placental development. (2/69323)We have identified a novel gene in a gene trap screen that encodes a protein related to the DnaJ co-chaperone in E. coli. The gene, named Mrj (mammalian relative of DnaJ) was expressed throughout development in both the embryo and placenta. Within the placenta, expression was particularly high in trophoblast giant cells but moderate levels were also observed in trophoblast cells of the chorion at embryonic day 8.5, and later in the labyrinth which arises from the attachment of the chorion to the allantois (a process called chorioallantoic fusion). Insertion of the ROSAbetageo gene trap vector into the Mrj gene created a null allele. Homozygous Mrj mutants died at mid-gestation due to a failure of chorioallantoic fusion at embryonic day 8.5, which precluded formation of the mature placenta. At embryonic day 8.5, the chorion in mutants was morphologically normal and expressed the cell adhesion molecule beta4 integrin that is known to be required for chorioallantoic fusion. However, expression of the chorionic trophoblast-specific transcription factor genes Err2 and Gcm1 was significantly reduced. The mutants showed no abnormal phenotypes in other trophoblast cell types or in the embryo proper. This study indicates a previously unsuspected role for chaperone proteins in placental development and represents the first genetic analysis of DnaJ-related protein function in higher eukaryotes. Based on a survey of EST databases representing different mouse tissues and embryonic stages, there are 40 or more DnaJ-related genes in mammals. In addition to Mrj, at least two of these genes are also expressed in the developing mouse placenta. The specificity of the developmental defect in Mrj mutants suggests that each of these genes may have unique tissue and cellular activities. (+info)
Requirement of a novel gene, Xin, in cardiac morphogenesis. (3/69323)A novel gene, Xin, from chick (cXin) and mouse (mXin) embryonic hearts, may be required for cardiac morphogenesis and looping. Both cloned cDNAs have a single open reading frame, encoding proteins with 2,562 and 1,677 amino acids for cXin and mXin, respectively. The derived amino acid sequences share 46% similarity. The overall domain structures of the predicted cXin and mXin proteins, including proline-rich regions, 16 amino acid repeats, DNA-binding domains, SH3-binding motifs and nuclear localization signals, are highly conserved. Northern blot analyses detect a single message of 8.9 and 5.8 kilo base (kb) from both cardiac and skeletal muscle of chick and mouse, respectively. In situ hybridization reveals that the cXin gene is specifically expressed in cardiac progenitor cells of chick embryos as early as stage 8, prior to heart tube formation. cXin continues to be expressed in the myocardium of developing hearts. By stage 15, cXin expression is also detected in the myotomes of developing somites. Immunofluorescence microscopy reveals that the mXin protein is colocalized with N-cadherin and connexin-43 in the intercalated discs of adult mouse hearts. Incubation of stage 6 chick embryos with cXin antisense oligonucleotides results in abnormal cardiac morphogenesis and an alteration of cardiac looping. The myocardium of the affected hearts becomes thickened and tends to form multiple invaginations into the heart cavity. This abnormal cellular process may account in part for the abnormal looping. cXin expression can be induced by bone morphogenetic protein (BMP) in explants of anterior medial mesoendoderm from stage 6 chick embryos, a tissue that is normally non-cardiogenic. This induction occurs following the BMP-mediated induction of two cardiac-restricted transcription factors, Nkx2.5 and MEF2C. Furthermore, either MEF2C or Nkx2.5 can transactivate a luciferase reporter driven by the mXin promoter in mouse fibroblasts. These results suggest that Xin may participate in a BMP-Nkx2.5-MEF2C pathway to control cardiac morphogenesis and looping. (+info)
Mechanisms of GDF-5 action during skeletal development. (4/69323)Mutations in GDF-5, a member of the TGF-beta superfamily, result in the autosomal recessive syndromes brachypod (bp) in mice and Hunter-Thompson and Grebe-type chondrodysplasias in humans. These syndromes are all characterised by the shortening of the appendicular skeleton and loss or abnormal development of some joints. To investigate how GDF-5 controls skeletogenesis, we overexpressed GDF-5 during chick limb development using the retrovirus, RCASBP. This resulted in up to a 37.5% increase in length of the skeletal elements, which was predominantly due to an increase in the number of chondrocytes. By injecting virus at different stages of development, we show that GDF-5 can increase both the size of the early cartilage condensation and the later developing skeletal element. Using in vitro micromass cultures as a model system to study the early steps of chondrogenesis, we show that GDF-5 increases chondrogenesis in a dose-dependent manner. We did not detect changes in proliferation. However, cell suspension cultures showed that GDF-5 might act at these stages by increasing cell adhesion, a critical determinant of early chondrogenesis. In contrast, pulse labelling experiments of GDF-5-infected limbs showed that at later stages of skeletal development GDF-5 can increase proliferation of chondrocytes. Thus, here we show two mechanisms of how GDF-5 may control different stages of skeletogenesis. Finally, our data show that levels of GDF-5 expression/activity are important in controlling the size of skeletal elements and provides a possible explanation for the variation in the severity of skeletal defects resulting from mutations in GDF-5.

Molecular cloning and epitope analysis of the peanut allergen Ara h 3. (5/69323)Peanut allergy is a significant IgE-mediated health problem because of the increased prevalence, potential severity, and chronicity of the reaction. Following our characterization of the two peanut allergens Ara h 1 and Ara h 2, we have isolated a cDNA clone encoding a third peanut allergen, Ara h 3. The deduced amino acid sequence of Ara h 3 shows homology to 11S seed-storage proteins. The recombinant form of this protein was expressed in a bacterial system and was recognized by serum IgE from approximately 45% of our peanut-allergic patient population. Serum IgE from these patients and overlapping, synthetic peptides were used to map the linear, IgE-binding epitopes of Ara h 3. Four epitopes, between 10 and 15 amino acids in length, were found within the primary sequence, with no obvious sequence motif shared by the peptides. One epitope is recognized by all Ara h 3-allergic patients. Mutational analysis of the epitopes revealed that single amino acid changes within these peptides could lead to a reduction or loss of IgE binding. By determining which amino acids are critical for IgE binding, it might be possible to alter the Ara h 3 cDNA to encode a protein with a reduced IgE-binding capacity. These results will enable the design of improved diagnostic and therapeutic approaches for food-hypersensitivity reactions. (+info)
TIF1gamma, a novel member of the transcriptional intermediary factor 1 family. (6/69323)We report the cloning and characterization of a novel member of the Transcriptional Intermediary Factor 1 (TIF1) gene family, human TIF1gamma. Similar to TIF1alpha and TIF1beta, the structure of TIF1beta is characterized by multiple domains: RING finger, B boxes, Coiled coil, PHD/TTC, and bromodomain. Although structurally related to TIF1alpha and TIF1beta, TIF1gamma presents several functional differences. In contrast to TIF1alpha, but like TIF1beta, TIF1 does not interact with nuclear receptors in yeast two-hybrid or GST pull-down assays and does not interfere with retinoic acid response in transfected mammalian cells. Whereas TIF1alpha and TIF1beta were previously found to interact with the KRAB silencing domain of KOX1 and with the HP1alpha, MODI (HP1beta) and MOD2 (HP1gamma) heterochromatinic proteins, suggesting that they may participate in a complex involved in heterochromatin-induced gene repression, TIF1gamma does not interact with either the KRAB domain of KOX1 or the HP1 proteins. Nevertheless, TIF1gamma, like TIF1alpha and TIF1beta, exhibits a strong silencing activity when tethered to a promoter. Since deletion of a novel motif unique to the three TIF1 proteins, called TIF1 signature sequence (TSS), abrogates transcriptional repression by TIF1gamma, this motif likely participates in TIF1 dependent repression.

Anopheles gambiae Ag-STAT, a new insect member of the STAT family, is activated in response to bacterial infection. (7/69323)A new insect member of the STAT family of transcription factors (Ag-STAT) has been cloned from the human malaria vector Anopheles gambiae. The domain involved in DNA interaction and the SH2 domain are well conserved. Ag-STAT is most similar to Drosophila D-STAT and to vertebrate STATs 5 and 6, constituting a proposed ancient class A of the STAT family. The mRNA is expressed at all developmental stages, and the protein is present in hemocytes, pericardial cells, midgut, skeletal muscle and fat body cells. There is no evidence of transcriptional activation following bacterial challenge. However, bacterial challenge results in nuclear translocation of Ag-STAT protein in fat body cells and induction of DNA-binding activity that recognizes a STAT target site. In vitro treatment with pervanadate (vanadate and H2O2) translocates Ag-STAT to the nucleus in midgut epithelial cells. This is the first evidence of direct participation of the STAT pathway in immune responses in insects. (+info)
In vivo expression of the nucleolar group I intron-encoded I-dirI homing endonuclease involves the removal of a spliceosomal intron. (8/69323)The Didymium iridis DiSSU1 intron is located in the nuclear SSU rDNA and has an unusual twin-ribozyme organization. One of the ribozymes (DiGIR2) catalyses intron excision and exon ligation. The other ribozyme (DiGIR1), which along with the endonuclease-encoding I-DirI open reading frame (ORF) is inserted in DiGIR2, carries out hydrolysis at internal processing sites (IPS1 and IPS2) located at its 3' end. Examination of the in vivo expression of DiSSU1 shows that after excision, DiSSU1 is matured further into the I-DirI mRNA by internal DiGIR1-catalysed cleavage upstream of the ORF 5' end, as well as truncation and polyadenylation downstream of the ORF 3' end. A spliceosomal intron, the first to be reported within a group I intron and the rDNA, is removed before the I-DirI mRNA associates with the polysomes. Taken together, our results imply that DiSSU1 uses a unique combination of intron-supplied ribozyme activity and adaptation to the general RNA polymerase II pathway of mRNA expression to allow a protein to be produced from the RNA polymerase I-transcribed rDNA.

Molecular cloning - Wikipedia
Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. The use of the word cloning refers to the fact that the method involves the replication of one molecule to produce a population of cells with identical DNA molecules. Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA. Molecular cloning methods are central to many contemporary areas of modern biology and medicine. In a conventional molecular cloning experiment, the DNA to be cloned is obtained from an organism of interest, then treated with enzymes in the test tube to generate smaller DNA fragments. Subsequently, these fragments are then combined with vector DNA to generate recombinant DNA molecules. The recombinant DNA is then introduced into a host ...

A Modified MultiSite Gateway Cloning Strategy for Consolidation of Genes in Plants | SpringerLink
The genome information is offering opportunities to manipulate genes, polygenic characters and multiple traits in plants. Although a number of approaches have been developed to manipulate traits in plants, technical hurdles make the process difficult. Gene cloning vectors that facilitate the fusion, overexpression or down regulation of genes in plant cells are being used with various degree of success. In this study, we modified gateway MultiSite cloning vectors and developed a hybrid cloning strategy which combines advantages of both traditional cloning and gateway recombination cloning. We developed Gateway entry (pGATE) vectors containing attL sites flanking multiple cloning sites and plant expression vector (pKM12GW) with specific recombination sites carrying different plant and bacterial selection markers. We constructed a plant expression vector carrying a reporter gene (GUS), two Bt cry genes in a predetermined pattern by a single round of LR recombination reaction after restriction ...

Chapter Summary | Texas Gateway
Nucleic acids can be isolated from cells for the purposes of further analysis by breaking open the cells and enzymatically destroying all other major macromolecules. Fragmented or whole chromosomes can be separated on the basis of size by gel electrophoresis. Short stretches of DNA or RNA can be amplified by PCR. Southern and northern blotting can be used to detect the presence of specific short sequences in a DNA or RNA sample. The term cloning may refer to cloning small DNA fragments (molecular cloning), cloning cell populations (cellular cloning), or cloning entire organisms (reproductive cloning). Genetic testing is performed to identify disease-causing genes, and gene therapy is used to cure an inheritable disease.. Transgenic organisms possess DNA from a different species, usually generated by molecular cloning techniques. Vaccines, antibiotics, and hormones are examples of products obtained by recombinant DNA technology. Transgenic plants are usually created to improve characteristics of ...

Comparison of human LTA4 hydrolase revealed 93% homology, and include zinc-binding motifs of aminopeptidases. COS-7 cells transfected with the cDNA revealed substantial LTA4 hydrolase activity, and their activities were abolished by preincubation with captopril, representing the first reported cDNA expression of recombinant enzyme in mammalian cells. RNA blot analysis indicated that LTA4 hydrolase was expressed in glomerular endothelial, epithelial and mesangial ...
Cloning and stable maintenance of 300-kilobase-pair fragments of human DNA in Escherichia coli using an F-factor-based vector. ...
A bacterial cloning system for mapping and analysis of complex genomes has been developed. The BAC system (for bacterial artificial chromosome) is based on Escherichia coli and its single-copy plasmid F factor. It is capable of maintaining human genomic DNA fragments of greater than 300 kilobase pairs. Individual clones of human DNA appear to be maintained with a high degree of structural stability in the host, even after 100 generations of serial growth. Because of high cloning efficiency, easy manipulation of the cloned DNA, and stable maintenance of inserted DNA, the BAC system may facilitate construction of DNA libraries of complex genomes with fuller representation and subsequent rapid analysis of complex genomic structure.. ...

Manufacturing Biotherapeutics - Starting with CHO Cloning - Cell Culture Dish
For every Herceptin, for every Enbrel, Humira and Rituxan, and for every successful biotherapeutic product in the market today, there is a long history of its product development. We all hope that our target protein product will make a difference in both the therapeutic market and the lives it will eventually affect as it reaches its ultimate goal of becoming a human therapeutic. The reality is, in order for it to be a feasible therapeutic, the protein must first be manufactured. And one of the very first steps in determining the manufacturing capability of the product is the crucial step of choosing the production cell line that will produce this protein.. There are many challenges in single cell CHO cloning procedures to obtain valuable stable CHO production cell lines. We often rely on efficient cloning strategies and cloning media to execute such a crucial task in the developmental process of a recombinant protein product. An important aspect of cloning strategies is the cloning media ...

The biosynthesis of steroid hormones is an integral component of insect growth, development and reproduction. Although there is an abundance of biochemical data implicating both microsomal and mitochondrial cytochrome P450s in steroid metabolism, molecular genetic information on mitochondrial P450s is almost entirely limited to vertebrate sequences. In the current study, a degenerate polymerase chain reaction (PCR) primer was targeted to the highly conserved region of P450 genes that encodes the heme-binding decapeptide. Using a 5 rapid amplification of cDNA ends (RACE) approach, seven novel cytochrome P450 genes were isolated from Drosophila acanthoptera, including one sequence (CYP12B1) with high regional homology to vertebrate mitochondrial P450s. Sequence analysis of the conceptual translation of the full length gene, obtained by 5RACE, revealed an amphipathic NH2-terminus rich in basic and hydrophilic amino acids, a characteristic feature of mitochondrial P450s that distinguishes them ...

Gene Cloning: A breakthrough - Orbit Biotech
During the last few decades, techniques for manipulating eukaryotic as well as prokaryotic DNA have witnessed a remarkable development. There are three main phases of the development of these techniques, which include recombinant DNA technology and gene cloning; polymerase chain reaction and DNA chips and microarrays. Using recombinant DNA technology, we can isolate and clone single copy of a gene or a DNA segment into an indefinite number of copies, all identical. This became possible, because bacteria, phages and plasmids reproduce in their usual style, even after insertion of foreign DNA, so that the inserted DNA also replicates faithfully with the parent DNA. This technique is called gene cloning. It involves the production of a large number of identical DNA molecules from a single ancestral DNA molecule. The essential characteristic of gene cloning is that the desired gene or DNA fragments must be selectively amplified resulting in a large increase in copy number of selected DNA sequences. ...

A ligation and restriction enzyme independent cloning technique: an alternative to conventional methods for cloning hard-to...
Reverse genetics is used in many laboratories around the world and enables the creation of tailor-made influenza viruses with a desired genotype or phenotype. However, the process is not flawless, and difficulties remain during cloning of influenza gene segments into reverse genetics vectors (pHW2000, pHH21, pCAGGS). Reverse genetics begins with making cDNA copies of influenza gene segments and cloning them into bi-directional (pHW2000) or uni-directional plasmids (pHH21, pCAGGS) followed by transfection of the recombinant plasmid(s) to HEK-293 T or any other suitable cells which are permissive to transfection. However, the presence of internal restriction sites in the gene segments of many field isolates of avian influenza viruses makes the cloning process difficult, if employing conventional methods. Further, the genetic instability of influenza gene-containing plasmids in bacteria (especially Polymerase Basic 2 and Polymerase Basic 1 genes; PB2 and PB1) also leads to erroneous incorporation of

Generating and Sequencing Full-length cDNAs of Novel Human Genes Within the German cDNA Consortium
P-57. Generating and Sequencing Full-length cDNAs of Novel Human Genes Within the German cDNA Consortium. Ruth E. Wellenreuther, Stefan Wiemann, Daniela Heiss, Nina Claudino, Annemarie Poustka, Department of Molecular Genome Analysis, German Cancer Research Center, Im Neuenheimer Heidelberg, GERMANY. We generate human cDNA libraries that are enriched in full length clones i.e. from the translation start to the poly A tail. These libraries are used for a) systematic sequencing within the cDNA consortium of the Genome Project aiming at the identification and analysis of as many new genes as possible and b) for screening to isolate full length clones of partial genes. Libraries are created by directional cloning of cDNAs into plasmid vectors. Full-length enrichment is achieved via Clontechs SMART technology. This method is PCR-based, and in our modified strategy, we amplify and clone selective size windows of the cDNA fraction above 3 kb.Clones from the libraries generated within this project are ...

GP-2 | Pancreapedia
The complete nucleotide and amino acid sequence of GP-2 was determined initially by molecular cloning technique from peptide sequence for rat, dog and humans (12, 13, 18, 43). The cDNA encodes a protein of 530 aa in humans with 67% identity to rat and 72% to dog GP-2. The primary sequence encodes 10 (human) or 8 (dog) Asn-linked glycosylation sites. This is consistent with data for in vitro translation by reticulocyte lysate that yields a protein of 55 kDa and treatment with N-glycanase which reduces the molecular mass of canine GP-2 from 75 kDa to 52 kDa (12, 18). Rat GP-2 has been shown to possess 5 or 6 N-linked high mannose carbohydrate chains (16). The primary protein sequence is also post-translationally glycosylated on its carboxyl terminal to a GPI moiety in the membrane during passage through the Golgi to reach the ZG (11, 13, 17). This GPI moiety contains a phosphoethanolamine linker attached to the protein, a 4-5 sugar core and a phosphatidylinositol whose hydrocarbon chains insert ...

Andre SzyszkowskiPsy 13004/28/05 Cloning: Choice is Ethical Thousands of people a year are placed on the organ donors list. Thousands of people a year are diagnosed with diseases that are dubbed fatal unless a transplant or transfusion is given. This has created a large demand for some alternative method to the present donor practice. Research in the taboos cience of cloning seems to provide a viable method in which to aid the problem aforementioned and many others as well. But is it ethical? Cloning technology is expected to aid the result in several medical breakthroughs. It is thought that there may one day be a cure for cancer. This is because the cloning process helps us understand the process of cell differentiation. Theories exist that if a cure for cancer can be found, then further testing may lead to a cure for heart attacks and cloning organs for organ transplantation. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and ...
Scientist: Cloning of humans unsafe - The Blade
44.38935 -68.20742 BAR HARBOR, Maine - New scientific evidence has heightened concerns about the safety of cloning human beings, an international authority warned yesterday.. We now believe that the potential to make a normal human baby with cloning is almost zero, said Dr. Rudolf Jaenisch, professor of biology at the Massachusetts Institute of Technology, at a genetics conference at Maines Jackson Laboratory.. Cloning a normal human is an illusion. There are major problems, and the problems are very serious.. Dr. Jaenisch, who helped pioneer gene transfer and cloning, said the public continues to be enthralled by stories of maverick doctors who supposedly plan to clone human beings.. Italian doctors in Rome, for instance, claim that they will clone a baby by next spring, with $500,000 provided by a couple whose infant died after heart surgery. An American firm called Clonaid has made repeated claims about a imminent human cloning.. Cloning a normal baby is utter nonsense, said Dr. ...

Introduction. Does cloning benefit or endanger society? Marley Gibbons-Balfour Case Study: Biology Contents Introduction 1 Background Science 2 Arguments against 4 Arguments for 7 Summary 10 Conclusion 11 Bibliography 12 Introduction Cloning has quickly become one of the most contentious issues in modern society, along with other issues like abortion, homosexuality and euthanasia. Due to the conflicted teachings and ideologies of many people in the world, there is no general consensus about cloning. Some people feel that it could benefit humans (through cures, through solving infertility and through knowledge), while others feel it could endanger humans and is a bad thing (due to ethical issues and due to being unaware of what could happen if it didnt work). Because of this, I have decided to investigate whether cloning actually does benefit or endanger society. I will go about this by collecting 6 sources (3 against cloning and 3 for cloning) and evaluating the evidence they present with the ...
Molecular Cloning and Biological Characterization of a Novel Murine Lymphoid Growth Factor | JEM
The cloning of a novel murine gene that encodes a protein with lymphopoietic activity is described. The activity was initially identified in a coculture system of an adherent thymic stromal cell line with a medullary phenotype, Z210R.1, and day 15 fetal liver (6). Interestingly, the nonadherent lymphoid-like cells that grew in these cocultures phenotypically resembled B cells. A clonal lymphoid line (NAG8/7) was derived from long term cocultures, and this line expresses B220, 6C3 (BP-1), and is surface μ+, but κ chain negative. Importantly, NAG8/7 cells proliferated in response to conditioned medium from the Z210R.1 cell line and thus became the basis of a bioassay that allowed for the preliminary characterization of the growth factor and the eventual cloning of the cDNA encoding this activity.. The cDNA encoding the NAG8/7 growth activity was cloned from a library made from the Z210R.1 cell line. Based on the nucleotide sequence, the mature TSLP protein consists of 121 amino acids with 3 ...

Multiple cloning site - Wikipedia
A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites - a standard feature of engineered plasmids. Restriction sites within an MCS are typically unique, occurring only once within a given plasmid. MCSs are commonly used during procedures involving molecular cloning or subcloning. Extremely useful in biotechnology, bioengineering, and molecular genetics, MCSs let a molecular biologist insert a piece of DNA or several pieces of DNA into the region of the MCS. This can be used to create transgenic organisms, also known as genetically modified organisms (GMOs). One bacterial plasmid used in genetic engineering as a plasmid cloning vector is pUC18. Its polylinker region is composed of several restriction enzyme recognition sites, that have been engineered into a single cluster (the polylinker). It has restriction sites for various restriction enzymes, including EcoRI, BamHI and PstI. Another vector used in genetic ...

A simple and efficient seamless DNA cloning method using SLiCE from Escherichia coli laboratory strains and its application to...
Both the colony formation rate (number of colonies) and the ratio of correct clones (cloning efficiency) in transformation are important determinants for efficient cloning of PCR fragments. Cell lysates from E. coli RecA− strains such as DH10B contain endogenous in vitro homologous recombination activity, and can be used to clone PCR fragments into vectors with homology regions. However, cloning with lysates from this strain is not efficient, particularly in the case of inserts with short homology lengths (approximately 15-20 bp), because of a lower colony formation rate . An E. coli PPY strain that expresses an optimized λ prophage Red/ET recombination system circumvents this problem by increasing the colony formation rate during PCR fragment cloning . To extend the utility of this method, I prepared SLiCE extracts from several E. coli laboratory strains with some modifications, and estimated the efficiency with which redox-related genes from Arabidopsis could then be cloned into ...

Cloning of Pig Cells - Tutor Me
There have been several successes of cloning especially the birth of Dolly the sheep in 1997, which lived for six years. Nuclear transfer involves the fusion of somatic cells and enucleated egg cells. Cloning of pig cells will be the focus of this paper. Scientists have identified pig clones as a potential hope for the future because of the possibility of xenotransplantation. Xenotransplantation has resulted from the merging of cloning with an additional biotechnology technique of genetic engineering. In addition, cloning has led to new prospects of livestock breeding and advances in medical procedures. This paper will discuss the procedure involved in the cloning of pig cells. Cloning is a multi-step process that scientists have endeavored to advance for a long time. The success story of Dolly the sheep served as a breakthrough for the cloning of mammalian cells after the success of other species (Cibell 2002, p. 32). Cloning has its basis on the understanding of the processes involved in ...

Molecular cloning and nucleotide sequence of a DNA fragment from Bacillus natto that enhances production of extracellular...
A DNA fragment from Bacillus natto IFO3936 has been cloned which enhances the production of both extracellular alkaline and neutral proteases in Bacillus subtilis. The DNA sequence analysis around the gene responsible for the hyperproduction, prtR, revealed one open reading frame (comprising 60 amino acid residues) which was bounded by potential transcriptional and translational regulatory signals in its preceding and following regions. This open reading frame was not homologous to the published sequences of the structural genes of the two proteases. The calculated molecular weight (7,109) of the polypeptide predicted from the DNA sequence is much smaller than those of the two proteases, indicating that the gene product is distinct from those enzymes. In-frame fusion between the N-terminal region of the coding sequence and the lacZ gene of Escherichia coli demonstrated that the coding region was indeed translated in vivo. By deletion analysis it was suggested that prtR was the structural gene ...

Using the pYES vector from Invitrogen we first deleted five forbidden restriction sites in the vector back bone via side directed mutagenesis. Furthermore the original multiple cloning site was replaced for a multiple cloning site compatible to the RFC 10/25 cloning standards. To allow easy extraction and purification of proteins for in vitro applications the new multiple cloning site allows to express proteins with a Strep-tag II. Exclusion of the galactose inducible promoter provided a powerful basis vector for the integration of user-defined promoters. This way the pTUM100 vector gives a valuable contribution to our and to further protein expression and promoter characterization experiments in the yeast Saccharomyces cerevisiae. Moreover we used the pTUM100 to integrate the three constitutive promoters Tef1, Tef2 and ADH which come all with different promoter intensities. ...

A one-step cloning method for the construction of somatic cell gene targeting vectors: application to production of human...
Gene targeting is a powerful method that can be used for examining the functions of genes. Traditionally, the construction of knockout (KO) vectors requires an amplification step to obtain two homologous, large fragments of genomic DNA. Restriction enzymes that cut at unique recognitions sites and numerous cloning steps are then carried out; this is often a time-consuming and frustrating process. We have developed a one-step cloning method for the insertion of two arms into a KO vector using exonuclease III. We modified an adeno-associated virus KO shuttle vector (pTK-LoxP-NEO-AAV) to yield pAAV-LIC, which contained two cassettes at the two multiple-cloning sites. The vector was digested with EcoRV to give two fragments. The two homologous arms, which had an overlap of 16 bases with the ends of the vector fragments, were amplified by polymerase chain reaction. After purification, the four fragments were mixed and treated with exonuclease III, then transformed into Escherichia coli to obtain the desired

Tools of Genetic Engineering | Boundless Microbiology
Scientists who do experimental genetics employ artificial selection experiments that permit the survival of organisms with user-defined phenotypes. Artificial selection is widely used in the field of microbial genetics, especially molecular cloning.. DNA recombination has been used to create gene replacements, deletions, insertions, inversions. Gene cloning and gene/protein tagging is also common. For gene replacements or deletions, usually a cassette encoding a drug-resistance gene is made by PCR.. Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. The use of the word cloning refers to the fact that the method involves the replication of a single DNA molecule starting from a single living cell to generate a large population of cells containing identical DNA molecules. Molecular cloning generally uses DNA sequences from two different organisms: the species that is the ...

Using a strategy based upon nucleotide sequence homology and starting from the sequence of the rat histamine H2 receptor (Ruat et al., Biochem. Biophys. Res. Commun. 1991, 179, 1470-1478), we have cloned a rat cDNA encoding a functional serotonin receptor (5-HT6). Its coding sequence corresponds to a glycoprotein of 436 amino acids displaying significant homology with other cloned monoaminergic receptors, e.g., various serotonin receptors. Genomic analysis of its gene indicated the presence of at least one intron. The major transcript of the 5-HT6 receptor gene has a size of approximately 4.1 kb but another minor 3.2 kb transcript was also evidenced. The highest expression, detected by Northern blot analysis as well as by in situ hybridization occurs in various serotoninergic areas of rat or guinea pig brain such as striatum, olfactory tubercle, nucleus accumbens and hippocampus, but a faint expression is also detectable in rat stomach. When transiently expressed in transfected COS-7 cells the 5-HT6

Molecular cloning, functional expression, and pharmacological characterization of 5-hydroxytryptamine3 receptor cDNA and its...
Polymerase chain reaction and rapid amplification of cDNA ends were used to isolate cDNAs encoding a 5-hydroxytryptamine3 (5-HT3) receptor subunit and its splice variants from guinea pig intestine. The amino acid sequence predicted from this cDNA is 81% homologous to the murine 5-HT3 receptor subunits cloned from NCB20 and N1E-115 cells. The splice variants code for two proteins differing by a deletion of six amino acids located in the large intracellular loop between transmembrane domains M3 and M4. For characterization, the cloned 5-HT3 cDNA was expressed in HEK 293 cells, and the electrophysiological and pharmacological properties of the recombinant ion/channel/receptor complex were investigated by patch clamping. Our data reveal that the cloned cDNAs code for guinea pig 5-HT3 receptors, which functionally assemble as homo-oligomers. The kinetic behavior of the ion channel and its sensitivity to several agonists and antagonists were markedly different from those of the cloned 5-HT3 receptors from

Abstract 【Aim】 This study aims to clone a C-type lectin gene from Plutella xylostella, to investigate its expression patterns and to elucidate its agglutination on bacteria. 【Methods】 Based on the bioinformatical analysis of genome and transcriptome database of P. xylostella, the full-length cDNA of a C-type lectin gene was cloned from P. xylostella by RT-PCR and rapid amplification of cDNA ends (RACE) techniques. Prokaryotic expression plasmid was constructed and the fusion protein was expressed in E.coli BL21. The polyclonal antibody with high serum titer was prepared using the purified fusion protein to immunize New Zealand white rabbit. Real-time quantitative PCR (RT-qPCR) was employed to analyze the expression profiles of this gene in different tissues (hemocyte, cuticle, fat body, midgut and Malpighiam tubules) of the day-1 4th instar larvae and different developmental stages （egg, 1st-4th instar larva, prepupa, pupa, and adult） of P. xylostella. RT-qPCR and Western blot were ...
A method for identifying genes within yeast artificial chromosomes: application to isolation of MLL fusion cDNAs from acute...
The majority of chromosomal translocations breakpoints are within regions of the genome where few DNA probes are available. The use of yeast artificial chromosomes (YACs) containing long stretches of human DNA allows dispersed DNA markers to be used to identify the position of breakpoints but does not readily allow subcloning of the precise breakpoint within the YAC DNA nor the cDNAs containing the affected genes. We describe a procedure allowing rapid isolation of cDNAs corresponding to genes within a YAC clone. Random cDNA is hybridised to PCR-generated biotinylated fragments of total DNA from a yeast strain harbouring a YAC clone. The hybrids can be recovered to facilitate subsequent cloning of the cDNA molecules. The application of this method to the cloning of cDNA molecules carrying sequences involved in the translocation t(4;11)(q21;q23) is illustrated.
The full-ORF clone resource of the German cDNA Consortium | BMC Genomics | Full Text
With the completion of the human genome sequence the functional analysis and characterization of the encoded proteins has become the next urging challenge in the post-genome era. The lack of comprehensive ORFeome resources has thus far hampered systematic applications by protein gain-of-function analysis. Gene and ORF coverage with full-length ORF clones thus needs to be extended. In combination with a unique and versatile cloning system, these will provide the tools for genome-wide systematic functional analyses, to achieve a deeper insight into complex biological processes. Here we describe the generation of a full-ORF clone resource of human genes applying the Gateway cloning technology (Invitrogen). A pipeline for efficient cloning and sequencing was developed and a sample tracking database was implemented to streamline the clone production process targeting more than 2,200 different ORFs. In addition, a robust cloning strategy was established, permitting the simultaneous generation of two clone

N2 - The Pat1 gene is expressed in the immature oocytes of Xenopus, and is reportedly involved in regulating the translation of maternal mRNAs required for oocyte-maturation. However, it is still unknown when Pat1a first appears in the differentiating ovary of amphibians. To address this issue, we isolated the full-length Pat1a cDNA from the frog Rana rugosa and examined its expression in the differentiating ovary of this frog. Among eight different tissues examined, the Pat1a mRNA was detectable in only the ovary. When frozen sections from the ovaries of tadpoles at various stages of development were immunostained for Vasa-a ...

February 6, 2003. SOUTH HADLEY, Mass.-Bacteria do it. Yeasts do it. Even some snails, shrimp, and aphids do it. But wait, while all of these creatures reproduce asexually through cloning, creating an exact replica of themselves, the cloning of more complex species, such as humans, still seems unnatural to many of us. Is it simply a case of getting used to a new technology, the way most of us got used to the idea of test tube babies over the past two decades? Or will reproductive cloning of humans ultimately be deemed unethical?. Questions such as these about cloning and stem-cell research-both for disease treatment and prevention and for reproduction-will be the focus of a series of events this spring on the theme, The Political Embryo: Reconceiving Human Reproduction, presented by Mount Holyoke Colleges Harriet L. and Paul M. Weissman Center for Leadership. In addition to a wide-ranging discussion of cloning, the series will look at the ethical and legal issues surrounding new and developing ...
Cloning, is it man playing god? - A-Level Science - Marked by Teachers.com
Introduction. 3845 ??? Cloning, is it man playing god? Cloning has become currently one of the hottest topics in society because of the laboratory-produced sheep Dolly, named after the country singer Dolly Patron. The birth of this little cloned sheep shocked society tremendously and created many controversial discussions. In the wake of this human cloning, religious leaders all over the world have condemned the action citing the reason that it is playing of god. However, we must understand that we at the Consortium that are involved in this effort are as human as anyone else. There is almost no difference between in-vitro fertilization (IVF) and cloning, other than the fact that the source of the genetic material is slightly different. Cloning is not playing of god, rather it is a salutary act which can fulfill human needs. ...read more. Middle.

What are the Risks of Animal Cloning? A look at the Disadvantages of the Cloning Process in Animals
The risks of animal cloning are immense. The cloning process is inefficient and cloned animals have been observed to have higher rates of infection, tumour growth, and skeletal abnormalities than normal offspring. Are the risks and disadvantages of cloning because it is a nascent technology that scientists are trying to get to grips with, or are there inherent problems with the cloning process?
