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

Question

Quizplus · Accepted Answer

A deletion mutation occurs when one or more nucleotides are removed from the DNA sequence. In this case, the sequence 5ʹ-A-C-G-T-A-C-G-T-3ʹ has been altered to 5ʹ-A-C-G-A-C-G-T-3ʹ by the removal of the nucleotide 'T'.
