Solution

The correct option is A Restriction endonuclease

Endonucleases are enzymes that produce internal cleavage in a DNA molecule. A class of endonulcleases cleave DNA only within or near those sites which have specific base sequences, such endonucleases are known as restriction endonucleses and the sites recognized by them are called restriction sites. With the discovery of restriction endonuclease, it was possible to extract the gene of interest with high precision and insert it into a vector.
