Synthesis, Cleavage and Sequence Analysis of DNA Complementary to the 26 S Messenger RNA of Sindbis Virus

Abstract

Conditions for synthesis of long complementary DNA transcripts of Sindbis virus 26 S and 49 S RNA in high yield have been developed. This single-stranded complementary DNA could be cut with HaeIII, HhaI, RsaI or TaqI to give reproducible patterns of discrete, virus-specific fragments that were suitable for subsequent end-labeling and direct sequence analysis. Using these methods we present the strategy used for obtaining nearly the entire 26 S RNA sequence from complementary DNA synthesized in vitro. This approach should prove useful for sequence analysis of any purified RNA available in microgram quantities.
