Question

Quizplus · Accepted Answer

A frameshift mutation occurs when a base is inserted into or deleted from a DNA sequence, completely altering the subsequent amino acid sequence. This can have a significant impact on the function of the resulting protein. The other answer choices (B, C, D, and E) do not involve the insertion or deletion of bases, and therefore would not result in a frameshift mutation.
