GinnyAnswer

Final answer:

Restriction enzymes are molecular cloning tools produced by bacteria to defend against viral infections.


Explanation:

Restriction enzymes, also known as restriction endonucleases, are molecular cloning tools that bacteria naturally produce to defend against viral infections. These enzymes recognize specific sequences in DNA, cut it, and prevent infections. The cut DNA can then be used in recombinant DNA technology to create new DNA molecules.
