Answer 2

Answer:

This question lacks options, the options are:

a. AGC TCG

b. AGC TTA TAG

c. TTA TCG

d. AGC TTT CG

The answer is D.

Explanation:

A frameshift mutation is a type of mutation in which the order at which the sequence is read becomes altered. In other words, a mutation is said to be "FRAME SHIFT" if it alters the order of reading the sequence. Frameshift mutation is caused by either insertion or deletion mutation i.e indel

According to this question, a DNA segment has base order: AGC TTA TCG. Deletion mutation will cause one or more nucleotide to be removed, hence, affecting the order of reading the sequence (reading frame). For example, in AGC TTT CG, nucleotide base A has been removed via deletion mutation, causing the reading sequence to shift.
