A DNA segment has bass order AGG TTA TCG. Which copy exhibits a frame shift mutation through deletion?

A) AGC TTA TAG
B) AGC TTT CG
C) TTA TCG
D) AGC TCG

1 answer

The correct answer is C) TTA TCG.

In a frame shift mutation through deletion, one or more nucleotides are deleted from the DNA sequence. In this case, the original DNA sequence is AGG TTA TCG. Deleting the first two nucleotides "AG" would result in the sequence TTA TCG, which matches option C.
