Question

Given the gene sequence ACGGCATTCGTACGT, which of the following choices would represent an insertion mutation?
A. ACGACATTCGTACGT
B. GCAGCATTCGTACGT
C. ACGGCATCGTACGT
D. ACGGCATATCGTACGT

Answer 1

Answer:

D.ACGGCATATCGTACGT

Explanation:

D because ACGGCATATCGTACGT the A in between the 2 t's was added

Answer 2

Answer: Option D

Explanation:

An insertion mutation can be defined as the addition of one or more nucleotide base pair into a  sequence of DNA.

This can happen in the micro satellite region of the DNA due to DNA polymerase slipping.

In this case the original sequence is ACGGCATTCGTACGT, insertion A in between T shows insertion mutation.
