a cross-hybridization of polysomal poly ( a ) + rna from liver of rats fed the hepatocarcinogen 3'-methyl-4-dimethylaminoazobenzene and from liver of control animals with their complementary dna has shown , that the disruption of the processing and/or release of nuclear rna induced by the carcinogen is not reflected in a change in the polysomal poly ( a ) + rna .
