Question

Quizplus · Accepted Answer

Restriction enzymes (or restriction endonucleases) are used by bacteria as a defense mechanism against bacteriophages. These enzymes recognize specific DNA sequences and cleave the DNA, thereby preventing the virus from replicating within the host cell. This is known as the restriction modification system. Reverse transcriptase, phosphofructokinase, DNA polymerase, and DNA ligase do not play a significant role in bacterial defense against bacteriophage.
