Introduction. The use of recombinant DNA technology can only benefit humans Recombinant DNA technology is the combining of the DNA from one organism with DNA from another organism. There are many steps in creating recombinant DNA. It begins with the isolation of a gene of interest. This gene is cut using restriction enzyme which will cut the gene in a particular place. A vector is taken and cut open with the same restriction enzyme as the gene was cut with. A vector is a piece of DNA that is capable of growth. Common vectors are of that of a bacterial plasmid. Once vector and gene have been cut they are joined at their sticky ends by using DNA ligase. The viruses and transgenic bacteria used as vectors in the recombinant DNA technology could undergo mutilation which could produce a new pathogen which we wont be able to control. Recombinant DNA technology can have many benefits to humans; one of these benefits is the process of gene therapy. Gene therapy is a way of treating disease by either ...
Introduction. Andrew Scarborough Definitions of Recombinant DNA technology Recombinant DNA technology, or genetic engineering, is artificially manipulating and modifying nucleic acid molecules to modify an organism or population of organisms, using a wide range of techniques and often involving heredity and reproduction. Some of the genetic engineering techniques involved in humans and animals include artificial insemination, in vitro fertilization (e.g., test-tube babies), sperm banks, cloning, and gene manipulation. The subject of genetic engineering, or recombinant DNA technology, is a difficult subject to take on because of the complex, ethical values surrounding the subject. Genetic engineering has advanced the understanding of many theoretical and practical aspects of gene function and organization. Saying that the use of recombinant DNA can only benefit humans may be correct in some ways, however there are many known negative sides to the argument of whether it should be carried out or ...

Recombinant DNA technology - Creating the clone: The steps in cloning are as follows. DNA is extracted from the organism under study and is cut into small fragments of a size suitable for cloning. Most often this is achieved by cleaving the DNA with a restriction enzyme. Restriction enzymes are extracted from several different species and strains of bacteria, in which they act as defense mechanisms against viruses. They can be thought of as

The vector DNA (plasmid) containing the "new" genes must now be inserted into host cells. The cells are made porous to DNA by a number of techniques and become transformed as they take up the recombinant DNA molecule. A group of genetically identical cells, all containing the same recombinant DNA molecule are called clones. The unique gene recombination now may be replicated and expressed by these cells. The students will simulate recombinant DNA techniques and make a polyvalent vaccine paper model. The term polyvalent refers to the ability of a single virus to impart immunity to another, unrelated virus. Immunity is developed against foreign antigens which are molecules that are not recognized as "self". For viruses, antigens are often the protein coat. If the gene for the major antigen of one virus is spliced or cloned into a second nonvirulent virus and that antigen is expressed (the protein is made) then this recombinant virus will immunize a host against both. To date several antigens have ...

Step 3 Link the DNA fragment to be cloned to the cloning vector to yield a recombinant DNA. Recombinant DNA, the general name for taking a piece of one strand of DNA and combining it with another strand is sometimes referred to as a "chimera". By combining two or more different strands of DNA by using the enzyme DNA ligase scientists are able to create a new strand of DNA. The most common recombinant process involves combining DNA of two different organisms. The ability to produce recombinant DNA molecules has not only revolutionized the study of genetics, but has laid the foundation for much of the biotechnology industry. The availability of human insulin for people with diabetes, human factor VIII for males with hemophilia, and other proteins used in human therapy were all made possible by recombinant DNA.. Step 4 Insert the recombinant DNA into a host cell which will provide the enzymatic machinery for DNA replication. When plasmids are used as cloning vectors, they can be introduced into ...

Have students compare the sequence of base pairs on an enzyme card with the sequences of the plasmid base pairs. If they find the same sequence of pairs on both the enzyme card and the plasmid strip, they should mark the location on the plasmid with a pencil, and write the enzyme number in the marked area. They should do this for each enzyme card. You may wish to point out that some enzyme sequences may not have a corresponding sequence on the plasmid, and that some enzyme sequences may have more than one corresponding sequence on the plasmid ...

Recombinant DNA is used in vaccines that involve the direct injection of genetic material into the human body. This genetic material is in the form of a plasmid, or loop of DNA, from the foreign antigen that is the target of the vaccination. After it is injected through our muscle tissue, our cells take in the DNA and begin to produce the foreign proteins encoded in the plasmids. These proteins promote our bodies´ immune responses to the targeted antigen. DNA vaccinations could become less costly to produce, are potentially safer and are theoretically longer lasting than alternative forms of vaccinations. ...
Not all cells take up the recombinant DNA. Geneticists want only cells that have been transformed with the recombinant DNA. In order to do this they select cells that have taken up the DNA by killing cells that have not. Recombinant DNA usually contains an antibiotic-resistant gene that gives any cells that take it up the ability to survive in the presence of a strong antibiotic. Any cells that do not take up the recombinant DNA are killed by the antibiotic ...

Tuesday - We will finish watching The Human Race, and then conduct an experiment investigating how recombinant DNA is made. Recombinant DNA is a DNA molecule that contains the DNA from two different organisms mixed together. For example, human insulin can be made by bacteria now because scientists have genetically engineered bacteria that contain the gene for producing human insulin. When the bacteria grow, they produce human insulin, and since they can reproduce about once every 20 minutes, it does not take too long before there are millions and millions of bacteria producing insulin! Homework will be to complete the recombinant DNA activity ...

We have previously described the purification of a heparin binding growth factor from adult bovine brain named heparin affin regulatory peptide (HARP), which was identical to an uterus derived growth factor named pleiotrophin and to a developmentally regulated neurite promoting factor named heparin-binding growth associated molecule. However, for yet unclear reasons, the mitogenic activity of this purified polypeptide following isolation from animal tissue extracts is a subject of controversy, due to conflicting and irreproducible data when produced by recombinant DNA technologies in E. coli or insect cells. The purified protein was inactive in mitogenic assays but the natural molecule was active in assay of neurite outgrowth. In order to clarify these conflicting results and to obtain a recombinant protein free from other contaminating heparin-binding growth factors, we have cloned human cDNA encoding human HARP, engineered its expression in NIH 3T3 cells and characterised the resulting ...

This is the second of six programs in the FJCs Science in the Courtroom series. Professor Edward S. Mocarski, Jr., of Stanford University Medical School, builds upon his lecture in Part One of the series (Core Concepts of Microbiology) by explaining the basic recombinant DNA and gene-cloning methods used in the field of biotechnology. Mocarski explains how the universality of the genetic code makes it possible for scientists to recombine DNA, that is, take DNA from one organism and move it into another. He also explains how recombinant DNA concepts are used in the "expression" of human proteins into bacteria, a process in which a human coding sequence is taken and inserted into a bacterial context, allowing the bacteria to produce abundant supplies of a "foreign protein" (foreign to the bacteria) that can be of commercial and therapeutic use.. ...

Experiments using phage lambda provided early insights into important molecular mechanisms, including genetic recombination and the control of gene expression. Before recombinant DNA technology, the use of lambda, most particularly lambda transducing phages, illustrated the importance of cloning bacterial genes, already providing some insight into how to use cloned genes to advantage. Subsequently, lambda made significant contributions to recombinant DNA technology, including the early generation of genomic and cDNA libraries. More recently, lambda genes associated with recombination have enabled techniques referred to as recombineering to be developed. These techniques permit the refined manipulation, including mutation, of foreign genes in Escherichia coli and their subsequent return to the donor organism. ...
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. ...
Recombinant DNA technology, joining together of DNA molecules from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry. Since the focus of all genetics is the gene, the fundamental goal of laboratory geneticists is to isolate, characterize, and manipulate genes. Although it is relatively easy to isolate a sample of DNA from a collection of cells, finding a specific gene within this DNA sample can be compared to finding a needle in a haystack. Consider the fact that each human cell contains approximately 2 metres (6 feet) of DNA. Therefore, a small tissue sample will contain many kilometres of DNA. However, recombinant DNA technology has made it possible to isolate one gene or any other segment of DNA, enabling researchers to determine its nucleotide sequence, study its transcripts, mutate it in highly specific ways, and reinsert the modified sequence into a living organism." ...
