Quizplus · Accepted Answer

Frameshift mutations involve the addition or deletion of one or more base pairs, which shifts the reading frame of the mRNA and alters the amino acid sequence of the resulting protein. Substitution of nucleotides, codons, or amino acids may result in different types of mutations, but not necessarily frameshift mutations. Rearrangement of amino acids is not a type of mutation.
