Answer

Correct option: A.

Restriction endonuclease

The discovery of enzymes that could cut and paste $\text{DNA}$ made genetic engineering possible. Restriction enzymes are $\text{DNA}-$cutting enzymes found in bacteria and harvested from them for use. Because they cut within the molecule, they are often called restriction endonucleases. A restriction enzyme recognizes and cuts $\text{DNA}$ only at a particular sequence of nucleotides. So, restriction endonucleases are used for separation of genetic material.
