Which of the following are considered to be frameshift mutations?

Question

Quizplus · Accepted Answer

Frameshift mutations are mutations that involve insertion or deletion of nucleotides that are not in multiples of three. This disrupts the reading frame of the genetic code, resulting in a completely different amino acid sequence downstream of the mutation. Therefore, both deletions and insertions are frameshift mutations. Inversions, on the other hand, involve a reversal of the order of nucleotides but do not disrupt the reading frame and are therefore not frameshift mutations.
