A nucleic acid sequence that contains an above average number of ADENINE and THYMINE bases.
The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.
The relative amounts of the PURINES and PYRIMIDINES in a nucleic acid.
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.
A nucleic acid sequence that contains an above average number of GUANINE and CYTOSINE bases.
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).
The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.

Clustered adenine/thymine stretches are essential for function of a fission yeast replication origin. (1/203)

We have determined functional elements required for autonomous replication of the Schizosaccharomyces pombe ars2004 that acts as an intrinsic chromosomal replication origin. Internal deletion analysis of a 940-bp fragment (ars2004M) showed three regions, I to III, to be required for autonomously replicating sequence (ARS) activity. Eight-base-pair substitutions in the 40-bp region I, composed of arrays of adenines on a DNA strand, resulted in a great reduction of ARS activity. Substitutions of region I with synthetic sequences showed that no specific sequence but rather repeats of three or more consecutive adenines or thymines, without interruption by guanine or cytosine, are required for the ARS activity. The 65-bp region III contains 11 repeats of the AAAAT sequence, while the 165-bp region II has short adenine or thymine stretches and a guanine- and cytosine-rich region which enhances ARS activity. All three regions in ars2004M can be replaced with 40-bp poly(dA/dT) fragments without reduction of ARS activity. Although spacer regions in the ars2004M enhance ARS activity, all could be deleted when an 40-bp poly(dA/dT) fragment was added in place of region I. Our results suggest that the origin activity of fission yeast replicators depends on the number of adenine/thymine stretches, the extent of their clustering, and presence of certain replication-enhancing elements.  (+info)

The centromeric sister chromatid cohesion site directs Mcd1p binding to adjacent sequences. (2/203)

Cohesion between sister chromatids occurs along the length of chromosomes, where it plays essential roles in chromosome segregation. We show here that the centromere, a cis-acting cohesion factor, directs the binding of Mcd1p, a cohesin subunit, to at least 2 kb regions flanking centromeres in a sequence-independent manner. The centromere is essential for the maintenance as well as the establishment of this cohesin domain. The efficiency of Mcd1p binding within the cohesin domain is independent of the primary nucleotide sequence of the centromere-flanking DNA but correlates with high A + T DNA content. Thus, the function of centromeres in the cohesion of centromere-proximal regions may be analogous to that of enhancers, nucleating cohesin complex binding over an extended chromosomal domain of A + T-rich DNA.  (+info)

Nuclear protein binding at the beta-myosin heavy chain A/T-rich element is enriched following increased skeletal muscle activity. (3/203)

In adult mouse skeletal muscle, beta-myosin heavy chain (betaMyHC) gene expression is primarily restricted to slow-type I fibers but can be induced in fast-type II fibers by mechanical overload (MOV). Our previous transgenic analyses have delimited an 89-base pair (bp) MOV-responsive region (-293 to -205), and shown that mutation of the MCAT and C-rich elements within this region did not abolish betaMyHC transgene induction by MOV. In this study we describe an A/T-rich element (betaA/T-rich; -269 5'-GGAGATATTTTT-3' -258) located within this 89-bp region that, only under MOV conditions, revealed enriched binding as characterized by electrophoretic mobility shift assays and dimethyl sulfate and diethyl pyrocarbonate interference footprinting. Direct, competition, and supershift electrophoretic mobility shift assays revealed highly enriched specific binding activity at the betaA/T-rich element that was antigenically distinct from GATA-4, MEF2A-D, SRF, and Oct-1, nuclear proteins that were previously shown to bind A/T-rich elements. In vitro translated GATA-4, MEF2C, SRF, and Oct-1 bound to consensus GATA, MEF2, SRE, and Oct-1 elements, respectively, but not to the betaA/T-rich element. Two-dimensional UV cross-linking of the bromodeoxyuridine-substituted betaA/T-rich element with mechanically overloaded plantaris (MOV-P) nuclear extract detected two proteins (44 and 48 kDa). Our results indicate that the betaA/T-rich element may function in vivo as a betaMyHC MOV-inducible element during hypertrophy of adult skeletal muscle by binding two distinct proteins identified only in MOV-P nuclear extract.  (+info)

Sequence evolution in bacterial endosymbionts having extreme base compositions. (4/203)

A major limitation on ability to reconstruct bacterial evolution is the lack of dated ancestors that might be used to evaluate and calibrate molecular clocks. Vertically transmitted symbionts that have cospeciated with animal hosts offer a firm basis for calibrating sequence evolution in bacteria, since fossils of the hosts can be used to date divergence events. Sequences for a functionally diverse set of genes have been obtained for bacterial endosymbionts (Buchnera) from two pairs of aphid host species, each pair diverging 50-70 MYA. Using these dates and estimated numbers of Buchnera generations per year, we calculated rates of base substitution for neutral and selected sites of protein-coding genes and overall rates for rRNA genes. Buchnera shows homogeneity among loci with regard to synonymous rate. The Buchnera synonymous rate is about twice that for low-codon-bias genes of Escherichia coli-Salmonella typhimurium on an absolute timescale, and fourfold higher on a generational timescale. Nonsynonymous substitutions show a greater rate disparity in favor of Buchnera, a result consistent with a genomewide decrease in selection efficiency in Buchnera. Ratios of synonymous to nonsynonymous substitutions differ for the two pairs of Buchnera, indicating that selection efficiency varies among lineages. Like numerous other intracellular bacteria, such as Rickettsia and Wolbachia, Buchnera has accumulated amino acids with codons rich in A or T. Phylogenetic reconstruction of amino acid replacements indicates that replacements yielding increased A + T predominated early in the evolution of Buchnera, with the trend slowing or stopping during the last 50 Myr. This suggests that base composition in Buchnera has approached a limit enforced by selective constraint acting on protein function.  (+info)

Cell type-specific autoregulation of the Caudal-related homeobox gene Cdx-2/3. (5/203)

The caudal-related homeobox gene Cdx-2/3 is a critical "master" control gene in embryogenesis. Mice heterozygous for a null mutation in Cdx-2/3 exhibit multiple malfunctions including tail abnormalities, stunted growth, a homeotic shift in vertebrae, and the development of multiple intestinal adenomatous polyps, indicating that Cdx-2/3 is haplo-insufficient. In vitro studies have identified more than a half-dozen downstream target genes expressed in pancreatic and intestinal cells for this transcription factor. We have examined the transcriptional properties of the mouse Cdx-2/3 promoter. This promoter could be autoregulated in pancreatic and intestinal cells that express endogenous Cdx-2/3. In contrast, Cdx-2/3 transfection represses the Cdx-2/3 promoter in fibroblasts, which do not express endogenous Cdx-2/3. Since Cdx-2/3 activates proglucagon gene promoter in both pancreatic and intestinal cells and in fibroblasts, we suggest that some, yet to be identified, cell type-specific components are required for activating selected target gene promoters of Cdx-2/3, including the Cdx-2/3 promoter itself. Cdx-2/3 binds to the TATA box and another AT-rich motif, designated as DBS, within an evolutionarily conserved proximal element of the Cdx-2/3 promoter. The DBS motif is critical for the autoregulation, whereas the TATA box may act as an attenuating element for the autoregulatory loop. Finally, overexpression of Cdx-2/3 in a pancreatic cell line activated the expression of the endogenous Cdx-2/3. Taken together, our results indicate that the dose-dependent phenotype of Cdx-2/3 expression on its downstream targets in vivo could be regulated initially via a transcriptional network involving cell type-specific autoregulation of the Cdx-2/3 promoter.  (+info)

Host sequences flanking the human T-cell leukemia virus type 1 provirus in vivo. (6/203)

Human pathogenic retroviruses do not have common loci of integration. However, many factors, such as chromatin structure, transcriptional activity, DNA-protein interaction, CpG methylation, and nucleotide composition of the target sequence, may influence integration site selection. These features have been investigated by in vitro integration reactions or by infection of cell lines with recombinant retroviruses. Less is known about target choice for integration in vivo. The present study was conducted in order to assess the characteristics of cellular sequences targeted for human T-cell leukemia virus type 1 (HTLV-1) integration in vivo. Sequencing integration sites from >/=200 proviruses (19 kb of sequence) isolated from 29 infected individuals revealed that HTLV-1 integration is not random at the level of the nucleotide sequence. The virus was found to integrate in A/T-rich regions with a weak consensus sequence at positions within and without of the hexameric repeat generated during integration. These features were not associated with a preference for integration near active regions or repeat elements of the host chromosomes. Most or all of the regions of the genome appear to be accessible to HTLV-1 integration. As with integration in vitro, integration specificity in vivo seems to be determined by local features rather than by the accessibility of specific regions.  (+info)

Start sites of bidirectional DNA synthesis at the human lamin B2 origin. (7/203)

The initiation sites of bidirectional synthesis at the DNA replication origin located at the 3' end of the human lamin B2 gene were investigated. RNA-primed nascent DNA molecules were subjected to second-strand synthesis with appropriate primers, amplified by ligation-mediated polymerase chain reaction, and size fractionated. Evidence for precise start sites was obtained. Exploration of close to 1 kilobase, coupled to inhibition of Okazaki fragment synthesis, demonstrates that the leading strands initiate at precise nucleotides on either helix, overlapping by three base pairs, within the area bound to a protein complex possibly analogous to the prereplicative complex of yeast.  (+info)

AT-rich palindromes mediate the constitutional t(11;22) translocation. (8/203)

The constitutional t(11;22) translocation is the only known recurrent non-Robertsonian translocation in humans. Offspring are susceptible to der(22) syndrome, a severe congenital anomaly disorder caused by 3&rcolon;1 meiotic nondisjunction events. We previously localized the t(11;22) translocation breakpoint to a region on 22q11 within a low-copy repeat termed "LCR22" and within an AT-rich repeat on 11q23. The LCR22s are implicated in mediating different rearrangements on 22q11, leading to velocardiofacial syndrome/DiGeorge syndrome and cat-eye syndrome by homologous recombination mechanisms. The LCR22s contain AT-rich repetitive sequences, suggesting that such repeats may mediate the t(11;22) translocation. To determine the molecular basis of the translocation, we cloned and sequenced the t(11;22) breakpoint in the derivative 11 and 22 chromosomes in 13 unrelated carriers, including two de novo cases and der(22) syndrome offspring. We found that, in all cases examined, the reciprocal exchange occurred between similar AT-rich repeats on both chromosomes 11q23 and 22q11. To understand the mechanism, we examined the sequence of the breakpoint intervals in the derivative chromosomes and compared this with the deduced normal chromosomal sequence. A palindromic AT-rich sequence with a near-perfect hairpin could form, by intrastrand base-pairing, on the parental chromosomes. The sequence of the breakpoint junction in both derivatives indicates that the exchange events occurred at the center of symmetry of the palindromes, and this resulted in small, overlapping staggered deletions in this region among the different carriers. On the basis of previous studies performed in diverse organisms, we hypothesize that double-strand breaks may occur in the center of the palindrome, the tip of the putative hairpin, leading to illegitimate recombination events between similar AT-rich sequences on chromosomes 11 and 22, resulting in deletions and loss of the palindrome, which then could stabilize the DNA structure.  (+info)

AT-rich sequence is a DNA sequence that is rich in adenine (A) and thymine (T) nucleotides. These sequences are often found in the non-coding regions of DNA, such as the intergenic regions between genes, and are thought to play a role in regulating gene expression. AT-rich sequences can form stable structures, such as hairpins and triplexes, due to the high number of hydrogen bonds that can be formed between A-T base pairs. These structures can affect the accessibility of DNA to transcription factors and other regulatory proteins, and can also affect the stability of the DNA molecule. In the medical field, AT-rich sequences are often studied in the context of diseases such as cancer, where changes in the structure or function of these sequences can lead to abnormal gene expression and contribute to the development and progression of the disease. They are also studied in the context of gene therapy, where they can be used as targets for the delivery of therapeutic genes to specific cells or tissues.

In the medical field, a base sequence refers to the specific order of nucleotides (adenine, thymine, cytosine, and guanine) that make up the genetic material (DNA or RNA) of an organism. The base sequence determines the genetic information encoded within the DNA molecule and ultimately determines the traits and characteristics of an individual. The base sequence can be analyzed using various techniques, such as DNA sequencing, to identify genetic variations or mutations that may be associated with certain diseases or conditions.

In the medical field, "Base Composition" refers to the relative proportions of the four nitrogenous bases (adenine, guanine, cytosine, and thymine) in DNA or RNA. The base composition of a nucleic acid molecule is determined by the number of each base present and the sequence in which they are arranged. The base composition of DNA is typically expressed as the percentage of each base relative to the total number of bases. For example, if a DNA molecule contains 100 bases and 30% of those bases are adenine, the base composition would be 30% A, 20% T, 20% C, and 30% G. The base composition of RNA is similar to that of DNA, but RNA contains the base uracil (U) instead of thymine (T). The base composition of RNA is typically expressed as the percentage of each base relative to the total number of bases, with the exception of uracil, which is often expressed as the percentage of each base relative to the total number of nucleotides (which includes both bases and sugars). The base composition of nucleic acids can provide important information about the genetic material and can be used to identify different types of organisms or to diagnose genetic disorders.

DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in living organisms. It is composed of four types of nitrogen-containing molecules called nucleotides, which are arranged in a specific sequence to form the genetic code. In the medical field, DNA is often studied as a tool for understanding and diagnosing genetic disorders. Genetic disorders are caused by changes in the DNA sequence that can affect the function of genes, leading to a variety of health problems. By analyzing DNA, doctors and researchers can identify specific genetic mutations that may be responsible for a particular disorder, and develop targeted treatments or therapies to address the underlying cause of the condition. DNA is also used in forensic science to identify individuals based on their unique genetic fingerprint. This is because each person's DNA sequence is unique, and can be used to distinguish one individual from another. DNA analysis is also used in criminal investigations to help solve crimes by linking DNA evidence to suspects or victims.
