The conversion step is characterized by its half-life of 10 to 12 weeks (in NMRI mice) and its independence from initiation. For conversion the mitogenic capacity of TPA appears to be necessary in addition to a specific effect of TPA (by which TPA differs qualita

Foods contain various types of mutagens and carcinogens, and contain both initiators and promoters of carcinogenesis. In general mutagens and carcinogens in food may be A. naturally occurring constituents especially in edible plants or spic

During the treatment of cell and early afterwards ALS are induced in DNA; they are removed from DNA by a repair mechanism with a half-life of about 3 hours. Between the 3rd and 6th hour after treatment, secondary ALS developed the repair of which had a half-life of 9 to

It has been stated that RNA has even a greater propensity for the covalent reaction with carcinogens than DNA. Of various species of RNA, tRNA seems to be most frequen

It thus appears that the lipid reacts with guanosine residues in the molecule of tRNA.. Initiator tRNA preparations pretreated with cholesteryl 14-methylhexadecanoate were charged significantly
