MutonenUKmuton[′myü‚tän]Mutonthe unit of mutation; the smallest section of a gene. Mutation is a change in a muton, leading to the emergence of a new, mutant form of a given organism. The terms “muton,” “cistron,” and “recon” were proposed by the American geneticist S. Benzer in 1957 to describe a definite gene function. The term “muton” later fell into disuse because it became clear that the muton corresponds to one pair of nucleotides in the DNA molecule and to a single nucleotide in viruses, which contain only single-stranded DNA or RNA. mutonenUKmu·ton(myū'ton),muton(myo͞o′tŏn′)mutonThe smallest unit of a gene capable of undergoing mutation, ranging in size from a single nucleotide substitution (causing point mutations), to deletions of large segments of DNA (causing frameshift mutations).mu·ton(myū'ton)mutonthe smallest part of a gene that can undergo a MUTATION.
