Frameshift mutations occur when the number of bases inserted or deleted is not a multiple of three.

Question

Quizplus · Accepted Answer

Frameshift mutations occur when one or more nucleotides are added or removed from a DNA sequence, causing a shift in the reading frame of the genetic code. This shift leads to changes in the resulting protein sequence and can have significant effects on gene function. When the number of bases inserted or deleted is not a multiple of three, it disrupts the codon reading frame and can result in a completely different amino acid sequence.
