Question

The natural function of restriction enzymes is to cut up foreign DNA. Who got the Nobel prize for their experiments on these enzymes?

• A. W. Arber and H. Smith
• B. D. Nathans
• C. Both A and B
• D. None of the above

Answer 1

Answer: (C)

Both A and B

Restriction endonuclease and its experiments were done by Arber, Smith, and Nathans who all were awarded the Nobel prize in 1978. They performed experiments proving that there are certain enzymes produced by the bacteria which help in the cleavage of the genomes of the pathogens.

So the correct answer is "Both A and B".
