Processes of Recombinant DNA Technology
Enable Autosuggest. Home Books Harper's Illustrated Biochemistry, 30e. Previous Chapter. Next Chapter. Weil P Weil, P. Rodwell V. Recombinant DNA is widely used in biotechnology , medicine and research. Today, recombinant proteins and other products that result from the use of DNA technology are found in essentially every western pharmacy, physician or veterinarian office, medical testing laboratory, and biological research laboratory.
In addition, organisms that have been manipulated using recombinant DNA technology, as well as products derived from those organisms, have found their way into many farms, supermarkets , home medicine cabinets , and even pet shops, such as those that sell GloFish and other genetically modified animals. The most common application of recombinant DNA is in basic research, in which the technology is important to most current work in the biological and biomedical sciences.
Recombinant proteins are widely used as reagents in laboratory experiments and to generate antibody probes for examining protein synthesis within cells and organisms. Many additional practical applications of recombinant DNA are found in industry, food production, human and veterinary medicine, agriculture, and bioengineering.
Cohen professor at Stanford University ; this patent was awarded in Scientists associated with the initial development of recombinant DNA methods recognized that the potential existed for organisms containing recombinant DNA to have undesirable or dangerous properties. At the Asilomar Conference on Recombinant DNA , these concerns were discussed and a voluntary moratorium on recombinant DNA research was initiated for experiments that were considered particularly risky.
Today, recombinant DNA molecules and recombinant proteins are usually not regarded as dangerous. However, concerns remain about some organisms that express recombinant DNA, particularly when they leave the laboratory and are introduced into the environment or food chain.
These concerns are discussed in the articles on genetically modified organisms and genetically modified food controversies. Furthermore, there are concerns about the by-products in biopharmaceutical production, where recombinant DNA result in specific protein products. The major by-product, termed host cell protein , comes from the host expression system and poses a threat to the patient's health and the overall environment. From Wikipedia, the free encyclopedia.

Coli, these signals must be E. Coli is unlikely to understand the signals of human promoters and terminators. However, some proteins are too complex to be produced in bacterium, so eukaryotic cells must be used. Recombinant DNA has been gaining in importance over the last few years, and recombinant DNA will only become more important in the 21st century as genetic diseases become more prevelant and agricultural area is reduced.
