Restriction enzymes are especially useful for genetic recombination work for all of the following reasons, except :
A) They cut DNA in the middle of specific sequences.
B) They cut DNA independent of the source of the DNA.
C) They often generate single stranded tails or "sticky ends".
D) There are a large variety of them commercially available.
E) All of these traits make restriction enzymes useful.

Question

Quizplus · Accepted Answer

Restriction enzymes are valued for their ability to cut DNA at specific sequences (A), their ability to cut DNA from any source (B), their production of "sticky ends" that facilitate the recombination of DNA fragments (C), and the wide variety available for different applications (D). Therefore, all of these traits contribute to their usefulness in genetic recombination work, making option E incorrect as it suggests these traits do not contribute to their utility.
