_____________ are able to degrade infecting bacteriophage DNA,thus protecting the host cell.

Question

Quizplus · Accepted Answer

Restriction endonucleases are enzymes that are able to recognize and cut specific DNA sequences, which are usually found in bacteriophage DNA. This makes it difficult for the bacteriophage DNA to infect and reproduce within the host cell. In addition, some restriction endonucleases also have a separate modification methylase activity, which methylates the same DNA sequence to protect the host cell's own DNA from being mistakenly cleaved by the restriction endonuclease.
