Recombinant DNA is widely used in biotechnology, medicine and research. Today, recombinant proteins and other products that result from the use of rDNA technology are found in essentially every western pharmacy, doctor's or veterinarian's office, medical testing laboratory, and biological research laboratory.
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.n addition to bacteria, other biotechnologists use yeast in recombinant DNA technology to make human insulin.
