Human insulin
Recombinant DNA allows scientists to reproduce a desired protein. Bacterium reproduce at a very fast rate, so they insert a desired protein into a bacterium by using restricti … on enzymes, and then the bacterium reproduces to produce a lot of that protein. Scientists can synthesize antibiotics with this technology.  Recombinant DNA technology enables individual fragments of DNA from any genome to be inserted into vector DNA molecules, such as plasmids, and individually amplified in bacteria. Each amplified fragment is called a DNA clone. The vector molecules with their inserts are called recombinant DNA because they consist of novel combinations of DNA from the donor genome (which can be from any organism) with vector DNA from a completely different source (generally a bacterial plasmid or a virus). A form of DNA produced by combining genetic material from two different sources by means of genetic engineering. Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.  Recombinant DNA (rDNA) molecules are DNA sequences that is a consequence of molecular cloning (used to assemble recombinant DNA molecules) to assemble the genetic material from various sources, making sequences that cannot be predicted in biological organisms. The term recombinant DNA means that two segments of DNA in a plasmid. Plasmids are those which generally occur in bacteria. Once a recombinant DNA is inserted into bacteria, these bacteria will make protein based on this recombinant DNA. The DNA sequences used in the construction of recombinant DNA molecules can originate from any species. For example, plant DNA may be joined to bacterial DNA, or human DNA may be joined with fungal DNA. Molecular cloning is the laboratory process used to create recombinant DNA. It is one of two widely used methods, along with polymerase chain reaction (PCR) used to direct the replication of any specific DNA sequence chosen by the experimentalist. Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera. Molecular cloning is the laboratory process used to create recombinant DNA. It is one of two widely used methods, along with polymerase chain reaction (PCR) used to direct the replication of any specific DNA sequence chosen by the experimentalist. Recombinant DNA: Example Using Insulin. Genetic engineering processes can make human insulin. Human insulin DNA is placed into the DNA of a second organism. The host organism becomes an insulin-producing factory. People with diabetes (called diabetics) do not correctly produce or use their insulin protein. The insulin protein helps control how much sugar is in your bloodstream. Millions of diabetics need to take insulin. Insulin from cows and pigs has been used since the early 1900s to treat diabetes. Construction of recombinant DNA, in which a foreign DNA fragment is inserted into a plasmid vector. In this example, the gene indicated by the white color is inactivated upon insertion of the foreign DNA fragment. Molecular cloning is the laboratory process used to create recombinant DNA. It is one of two widely used methods, along with polymerase chain reaction (PCR) used to direct the replication of any specific DNA sequence chosen by the experimentalist. Recombinant DNA technology provided a way for scientists to produce human insulin in the laboratory. The gene for human insulin is isolated from human cells and inserted into plasmids. These plasmids are then introduced into bacterial cells, which manufacture the insulin protein based on the human code. In addition to bacteria, other biotechnologists use yeast in recombinant DNA technology to make human insulin. Yeast can perform more of the complicated cellular processes that occur in human cells, making it a more useful organism for producing human substances.
