in order to better understand the carcinogenic process , a comparative study was undertaken of the association of nitrosamine-derived radioactivity with nuclear and mitochondrial dna isolated from tumor-susceptible and non-tumor-susceptible tissues of two strains of mice with different susceptibilities to tumor induction by dimethylnitrosamine ( dmn ) or diethylnitrosamine ( den ) .
