Question

When DNA replication occurs before meiosis, the original DNA strand GGT CTC CTC ACT CCA is copied into complementary strand CCA GAG GAG TAG GGT. What type of mutation has occurred?

Answer 1

the answer is inversion

Answer 2

The right answer is Inversion

The inversion mutation is a permutation of two or more neighboring deoxyribonucleotides, as is the case in this question.

Normally, the complementary strand is

GGT CTC CTC ACT CCA

CCA GAG GAG TGA GGT

Instead of

CCA GAG GAG TAG GGT (the bold part was "inverted").
