A) base analogs and frameshift
B) error prone and spontaneous
C) transversions and transitions
D) euchromatic and heterochromatic
E) sense and antisense

Answer 1

The two formal terms used to describe categories of mutational nucleotide substitutions in DNA are C) transversions and transitions. Hence, C) is correct.

Step-by-step explanation:

The two formal terms used to describe categories of mutational nucleotide substitutions in DNA are transversions and transitions.

Transitions refer to a purine or pyrimidine being replaced by a base of the same kind, while transversions refer to a purine being replaced by a pyrimidine, or vice versa.
