Mutations can change a polypeptide's amino acid sequence because the genetic code's degeneracy allows different triplets to code for the same amino acid.
Mutations can alter the amino acid sequence of a polypeptide because the genetic code is degenerate, meaning some amino acids are coded by multiple DNA triplets.

| Back | Degenerate nature of genetic code means some amino acids coded by more than one DNA triplet |
