When zero- point mutations were induced in the yeastSaccharomyces cerevisiae using ethyl methanesulfonate ( EMS) no differences were found in the frequency of auxotrophic mutants formed by a short and a prolonged treatment of the agent at equal survival level. Highly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning.

Ethyl methanesulfonate mutagenesis repair manuals. This typically produces only point mutations. Deletion of either gene abolishes most of the mutagenesis caused by a number of agents including UV, 4- nitroquinoline oxide, and methyl- methanesulfonate [ 20, 101, 102, 104– 110].

Is hydrolyzed by excess aqueous alkali to non- corrosive and non- toxic products. Gens, ethyl methanesulfonate ( EMS) is considered as an effective one because it can from adducts with nucleo- tides efficiently, resulting in mispairing these nucleotideamong s with their complementary bases and thus in- troducing base changes after replication [ 5].
