Specific termination of RNA polymerase synthesis as a method of RNA and DNA sequencing

Abstract
Termination of RNA synthesis with 3′-O-Methylnucleoside 5′-triphosphates have been studied using E.coli RNA polymerase holoenzyme and poly [d(A-T)] as well as unfractionated T7 D Δ III DNA as templates. It was shown that the termination can be used for DNA sequencing. A sequence of a part of RNA synthesized from AI promoter of the DNA have been determined. Syntheses of four 3′-O-Methylnucleoside 5′-triphosphates are described.
