What is the mechanism by which base analogs cause mutations

What is the mechanism by which base analogs cause mutations?

A. Depurination of guanines

D. Oxidation of guanine

C. Deamination of cytosine leading to uracil

B. Mispairing with normal bases

E. Intercalating between adjacent bases in DNA

Solution

The answer is: B. Mispairing with normal bases.

Base analogs mispairs with normal bases and can bring about mutation.
