title: Activation of the Ha-ras gene in C3H 10T1/2 cells transformed by exposure to N-methyl-N'-nitro-N-nitrosoguanidine.
abstract: A transfectable, presumably mutationally activated, c-Ha-ras gene was identified in a clonal population of 10T1/2 cells established from a Type II focus induced by exposure of a parental, wild-type population to N-methyl-N'-nitro-N-nitrosoguanidine (MNNG).
