Enzymes that recognize palindromic sequences of DNA, that are cut within the recognition sequence, that do not have methylating activity, and that are used frequently in the laboratory are which type of restriction enzymes?

Question

Quizplus · Accepted Answer

Type II restriction enzymes recognize palindromic sequences of DNA and cut within or near the recognition sequence. They do not have methylating activity and are commonly used in the laboratory. Type I and Type III restriction enzymes cut at sites away from the recognition sequence and require ATP hydrolysis for activity. Type IV restriction enzymes modify DNA without cutting it.
