Recombinant DNA

Recombinant DNA (rDNA) is an artificial form of DNA intentionally produced with molecular biology techniques that allow disparate sequences of DNA to be joined together. The first use of the rDNA technique dates back to 1973, when Stanley N. Cohen and his colleagues published an article detailing a technique for isolating and amplifying genes or DNA segments and inserting them into bacteria. The discovery that genes isolated from one organism that are transferred into another may be functional has opened the door to further important research in biology, not the least of which is the study of genes and their function in the biological processes of living organisms. Gene transfer techniques also provide the pharmaceutical and agrifood industries with important applications, already a part of ...
