A)cut straight through both strands of DNA.
B)cut through the DNA, leaving some overhang at both ends.
C)will alternate between cutting straight through both strands of DNA and leaving some overhang at both ends.
D)some of them will cut straight through, while others will leave an overhang at both ends of the cut.

Question

Quizplus · Accepted Answer

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut DNA at or near specific recognition sequences. Different restriction enzymes have different specificities for their recognition sequences. Some of them cut the DNA strands straight across, producing blunt ends, while others make staggered cuts, resulting in overhanging ends or "sticky ends." This variability allows for a wide range of applications in molecular biology, including cloning and DNA fragment analysis.
