Vedclass · Answer

(D) frame-shift mutation is a genetic mutation caused by the insertion or deletion of a number of nucleotides in a $DNA$ sequence that is not divisible by three.This shift in the reading frame results in the misreading of all subsequent codons,leading to the synthesis of a completely different protein.Deletion or insertion of one or more base pairs (that are not multiples of three) causes this shift.Therefore,both the deletion and duplication (insertion) of base pairs (if not in multiples of three) can result in a frame-shift mutation.
