Out of A-T,G-C pairing bases of DNA may exist in alternate valencyt state owing to arrangement calld

A

analogue substitution

B

tautomerisational mutation

C

frameshift mutation

D

point mutation

Text Solution

Verified by Experts

The correct Answer is:
B
Tautomerisation occurs through rearrangement of electrons and protons of the molecules. Due to this the purines and pyrimidines in DNA and RNA may exist in several alternate forms or tautomers.
