Quizplus · Accepted Answer

Restriction enzymes are used by bacteria to destroy viral DNA. These enzymes can recognize and cut specific sequences of DNA, which are usually found in the viral DNA. By cleaving the viral DNA at these specific sites, the restriction enzymes can prevent the virus from replicating and ultimately destroy it. This is an important defense mechanism for bacteria against viral infections.
