EFFECTS OF HUMAN BLOOD CONSTITUENTS ON FORMATION OF DNA-CARCINOGEN ADDUCTS AFdG REVEALED BY 32p-POSTLABELLING
《Chinese Science Bulletin》1990年第21期1827-1829,共3页沈建华 M.WEGENKE T.WOLFF 
The formation of DNA-adducts, i.e. the covalent modification of DNA molecules with carcinogens, is the initial event in carcinogenesis. In the organisms, most of the genotoxic chemicals must be first converted into el...
