Genetic codes are read in the sequence of 3. Insertion or deletion of a single base changes the reading frame of codon and is called frameshift mutation. However, insertion or deletion of three or its multiple bases insert or delete in one or multiple codon hence one or multiple amino acids and reading frame remains unaltered from that point onwards.
