Question

Quizplus · Accepted Answer

Restriction endonucleases are enzymes that recognize and cut DNA at specific target sequences, often called restriction sites. When a bacteriophage infects a bacterial cell, its DNA can be identified as foreign and attacked by the restriction endonucleases, which cleave the viral genome into smaller pieces and make it unable to replicate. This is part of a defense mechanism called the restriction-modification system, which helps protect the bacterial cell from being overrun by phages.
