An enzyme catalysing the removal of nucleotides from the ends of DNA is

A

endonuclease

B

exonuclease

C

DNA ligase

D

Hind - II.

Text Solution

Verified by Experts

The correct Answer is:
B
Exonucleases remove nucleotides from the ends of the DNA. Endonucleases make cuts at specific positions within the DNA. DNA ligase (also called genetic gum) is a sealing enzyme which is responsible for joining of two individual fragments of DNA, whereas Hind- II is the first discovered restriction endonuclease enzyme.
