Some bacteria,through natural selection,have acquired some extremely potent enzymes that destroy viral DNA,thereby preventing the bacterial cell from becoming infected with the virus.These enzymes are called:

Question

Quizplus · Accepted Answer

Restriction endonucleases are enzymes that can cut DNA molecules at specific sequences. Some have evolved in bacteria as a defense mechanism against viral infection. These enzymes can recognize and cut up viral DNA before it can take over the bacterial cell machinery for replication, preventing the infection from spreading. DNA polymerases are enzymes that are involved in copying DNA during replication, while DNA ligases are enzymes that can join together two DNA strands. Restriction ligases are not a known enzyme.
