How Does A Frameshift Mutation Affect The Protein
A frameshift mutation affects the protein by shifting the way a gene s DNA sequence is read during translation often changing every amino acid after the mutation and producing a shortened altered or nonfunctional protein These mutations happen when one or two nucleotides are inserted into or deleted
