title: Sindbis virus RNA replication. II. Strand composition and metabolic fate of the multi-stranded RNA species.
abstract: Double-stranded RNA from SB virus-infected cells was denatured and analysed on agarose-methylmercuric hydroxide gels. Equimolar amounts of three single-stranded species with mol. wt. of 4 x 10(6), 2.5 x 10(6) and 1.8 x 10(6) were found. Pulse and chase experiments in infected cells established a precursor-product relationship between the multi-stranded and single-stranded virus RNA species. The present results support the model in which the 49S and 26S species of virus RNA are synthesized in infected cells from two distinct replicating structures.
