Agent that include mutation are known as MUTAGENS. Mutagen may be different kind of radiation certain chemical . the different mutagen maybe group as follow

         1. Physical mutagen 

               A. Ionizing radiation

                      i) particulate radiation that include x-ray, gamma ray,beta Ray etc

                     ii) non particulate radiation              

              B.  Nonionizing radiation i.e                                           ultraviolet radiation

        2. Chemical mutagens

             A. Alkylating agent- i.e sulphur mustards, nitrogen mustards, epoxides, imines(ethylene imine or EI), sulphates and sulphonate (ethylmethane sulphonate or EMS,methylmethane sulphonate or MMS),diazoalkanes,nitroso compounds, N-methyl-N-nitro-N-nitroso-guanidine or MNNG)

             B. Acridine dyes- i.e acriflavine,proflavine,acridine orange,acridine yellow,ethidium bromide.

            C. Base analogues i.e 5-bromouracil,5-chlorouracil.

            D. other - nitrous acid, hydroxyl                                       amine, sodium aside
