Detailed explanation-1: -After preliminary experiments in 1973, the Cohen-Boyer team was able to cut open a plasmid loop from one species of bacteria, insert a gene from different bacterial species and close the plasmid. This created a recombinant DNA molecule–a plasmid containing recombined DNA from two different sources.
Detailed explanation-2: -Boyer and Stanley N. Cohen. By inventing recombinant-DNA technology Boyer and Cohen jump-started the biotechnology industry, including Genentech, which creates important applications for a wide range of medical uses.
Detailed explanation-3: -The first production of recombinant DNA molecules, using restriction enzymes, occurred in the early 1970s. Recombinant DNA technology involves the joining of DNA from different species and subsequently inserting the hybrid DNA into a host cell, often a bacterium.
Detailed explanation-4: -For instance, recombinant DNA technology has enabled scientists to identify an array of genes through gene mapping, as well as determining the roles of these genes in different organisms. An outstanding example is the application of recombinant DNA technology in studying the expression of genes in various organisms.
