we have further analyzed the metabolism of specific messenger ribonucleic acid ( mrna ) sequences within the cytoplasmic and nuclear rna of chinese hamster ovary ( cho ) cells by using a set of previously constructed complementary deoxyribonucleic acid ( dna ) clones ( harpold et al. , cell 17:1025-1035 , 1979 ) as specific molecular probes in a variety of rna : dna hybridization experiments .
