in contrast dna which was bound to the column was significantly depleted in sequences hybridizing with total cellular rna ( which contains mostly ribosomal rna ) and with sequences hybridizing to the 3'-terminal region of a cytochrome p-450 gene , which is inducible by the chemical carcinogen 3-methylcholanthrene , regardless of whether isolated from control or from carcinogen-treated rat livers .
