The first recombinant DNA was constructed by linking an antibiotic resistant gene with thte native plasmid of

Options

A. Escherichia coli
B. Salmonella typhimurium
C. Clostridium butylicum
D. Acetobacter acetic

Answer

b

Explanation

The construction of first recombinant DNA emerged from the linking of gene encoding antibiotic resistance gene with a native plasmid of Salmonella typhimurium.
It was accomplished by Stanley Cohen and Herbert Boyer in 1972. They isolated the antibiotic gene by cutting out a piece of DNA. This cutting of DNA at specific locations is carried out by molecular scissors also known as restriction enzymes.
