In heredity: Mechanisms of mutation
…amino acid are called “missense” mutations; these can lead to alteration or loss of protein function. A more severe type of base substitution, called a “nonsense” mutation, results in a stop codon in a position where there was not one before, which causes the premature termination of protein synthesis…

In point mutation
…are divided into silent mutations, missense mutations, and nonsense mutations. Silent mutations result in a new codon (a triplet nucleotide sequence in RNA) that codes for the same amino acid as the wild type codon in that position. In some silent mutations the codon codes for a different amino acid…
