Answer

  1. Restriction endonuclease

Explanation:

The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes are 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 DNA only at a particular sequence of nucleotides. So, restriction endonucleases are used for separation of genetic material.
