title: [Changes in the composition of double-stranded sequences of poly(A)-containing RNA in cell cytoplasm during hormonal induction].
abstract: Double-stranded segments (c-ds) have been studied in the poly(A)+ cytoplasmic rat liver RNA. Duplexes about 40 base pairs long have been shown to be of intermolecular character and originate from the interaction between ss-RNA and complementary regions of the poly(A)-containing RNA molecules. Shorter ds-sequences are, mainly, of intramolecular nature. Double-stranded sequences of different length differ also in their oligonucleotide composition, according to fingerprint analysis data. Under the action of cortisone, only several kinds of double-stranded sequences have been demonstrated to increase in the population of cytoplasmic poly(A)+RNA. The function of ds-regions in the hormonal regulation of gene expression is suggested.
