In genetics, a mutation is a change of the nucleotide sequence of the genome of an organismvirus, or extrachromosomal genetic element. Mutations result from unrepaired damage to DNA or to RNA genomes (typically caused by radiation or chemical mutagens), errors in the process ofreplication, or from the insertion or deletion of segments of DNA by mobile genetic elements.
