A

Mutagen

B

Mutation

C

Translation

D

recombination

Text Solution

Verified by Experts

The correct Answer is:
B
Change in the sequence of nucleotide in DNA is called as mutation. The point mutations involve minor changes in the genetic material, while macro mutations involve large segments of chromosomes. 'Frameshift mutation' includes the addition or deletion of nucleotide (not involving 3 base pairs) so that the reading frame of hte RNA is shifted to left or right during translation.
