D

✓
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.
