Ethyl methanesulfonate is a type of mutagen that has a chemical nature and is responsible for adding the alkyl groups i.e. methyl, ethyl etc. to the nitrogenous bases. The chemical formula of ethyl methanesulfonate is C3H8SO3. It is known to cause mutations, ageing as well as cancers in the body.
The random mutations are caused in the genes by the substitution of nucleotides. Mostly, the nucleotide that is affected by it is guanine. It is thought that EMS only produces point mutations. The rate at which the mutation in the gene is induced is 5x10−4 to 5x10−2/gene. The mutations caused by this can lead to many diseases.
