Mutations mutation is a change in dna, the hereditary material of lifean organism's dna affects how it looks, how it behaves, and its physiology — all aspects of its life. Mutation is a change in a dna sequence mutations can result from dna copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. This type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene nonsense mutation a nonsense mutation is also a change in one dna base pair instead of substituting one amino acid for another, however, the altered.
