A mutation (Section 14.1) is a change in the nucleotide sequence of a short region of a genome (Figure 14.1A). Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
