A Kinetic Analysis of the Synthesis in BHK 21 Cells of RNAs Specific for Semliki Forest Virus

Abstract

A kinetic analysis of formation of Semliki Forest virus-specific RNAs revealed that 22 S RNA was synthesized first and accumulated within or on a structure not disrupted by homogenization, but disrupted by detergent treatment, presumably a lipid-containing membrane or vesicle. When sampled at the end of the latent period of virus growth the 22 S RNA consisted of a mixture of two RNAs, double- and single-stranded. The amount of double-stranded 22 S RNA remained constant thereafter with no complementary RNA synthesized after the latent period of virus growth.
