Answer: They replace the original amino acid with the same or a chemically similar amino acid

Explanation:

If for instance: glutamate is replaced by aspartate in a polypeptide chain, then the mutation is called 'silent' because both glutamate and aspartate are acidic amino acids, hence it does not result in a change of the amino acid sequence of the protein.
