They're a defense mechanism found in bacteria that protects from viruses. They cut at palindromic sequences of DNA.

Explanation:

Restriction enzymes are so named because they restrict the number and ability of viruses to harm a bacterium. Restriction enzymes cut DNA at palindromic sequences, places where the nucleotides read the same forward and backwards. Restriction enzymes are used by scientists in a variety of research applications. Some common restriction enzymes are BAMH1, ECOR1, and HIND3
