Solution
The correct option is B Stanley Cohen
Stanley Cohen had developed a method of removing the plasmids from the bacterial cells and then reinserting them into other cells.
Plasmids refer to the extrachromosomal double-stranded DNA. A cell may have one or many copies of a particular type of plasmid.
Boyer studied many restriction enzymes related to E.coli. These enzymes were specific in their cutting locations.
Stanley Cohen and Herbert Boyer generated the first recombinant DNA molecule by combining a gene from a bacterium with a plasmid of Escherichia coli.
Work of both these scientists (Boyer and Cohen) helped to specifically isolate, insert segments of DNA in host cells and use them as factories to produce various products like plant proteins.
Craig Venter, an American geneticist and biochemist, pioneered new techniques in genetics and genomics research, especially in the Human Genome Project (HGP).
Hungarian engineer Karl Ereky first coined the term 'biotechnology' in 1919, meaning the production of products from raw materials with the aid of living organisms.
