Frameshift biology definition
WebHowever, frameshift mutation s, caused by insertions or deletions of a number of nucleotides that are not a multiple of three are extremely problematic because a shift in the reading frame results (Figure 11.18). Because ribosomes read the mRNA in triplet codons, frameshift mutations can change every amino acid after the point of the mutation.
