Imagine that a DNA sequence of 5ʹ-A-C-G-T-A-C-G-T-3ʹ is altered to 5ʹ-A-C-G-C-A-C-G-T-3ʹ. This could happen as a result of a(n)
A) insertion mutation.
B) deletion mutation.
C) translocation.
D) nucleotide substitution mutation.
E) inversion.

Question

Quizplus · Accepted Answer

The alteration from 5ʹ-A-C-G-T-A-C-G-T-3ʹ to 5ʹ-A-C-G-C-A-C-G-T-3ʹ involves changing a single nucleotide (T to C), which is characteristic of a nucleotide substitution mutation.
