WebA point mutation is a change to single DNA letter. They fall into three categories: Missense mutations cause a single amino acid change in the protein. Nonsense mutations make a premature "stop" codon. Any codons after that are not translated, and the resulting protein is missing amino acids. Silent mutations code for the same amino acid as before.
