What is the function of naturally occurring restriction enzymes in bacterial cells?

Question

Quizplus · Accepted Answer

Restriction enzymes in bacterial cells recognize and cleave DNA molecules that are foreign to the bacterial cell. This is a defense mechanism that helps the bacterial cell protect itself from foreign DNA, such as that from viruses or other bacteria.

Answer: A, B, and D are incorrect 
 None of these options accurately describe the function of naturally occurring restriction enzymes in bacterial cells. Option A is incorrect because restriction enzymes do not play a role in DNA replication, which is a separate process. Option B is incorrect because restriction enzymes do not degrade the bacterial cell's own DNA, but rather target foreign DNA. Option D is incorrect because it describes the function of ligase enzymes, which are separate from restriction enzymes.
