Quizplus · Accepted Answer

A frameshift mutation occurs when one or more nucleotides are either inserted or deleted from the DNA sequence. Therefore, the correct answer is D, which includes both deletion and insertion as possible causes of a frameshift mutation. Both missense and nonsense mutations can also occur, but they do not necessarily cause a frameshift.
