the effects of n-methyl- and n-ethyl-n'-nitro-n-nitrosoguanidines and methyl and ethyl methanesulfonates on dna synthesis in c3h/10t 1/2 mouse embryo fibroblasts and chinese hamster v79 cells have been analyzed by measuring the incorporation of tritiated thymidine into the trichloroacetic acid-insoluble fraction and the purified dna of the cells , and by measuring the fraction of parental dna replicated by equilibrium density sedimentation in neutral cesium chloride gradients .
