Using SP6 RNA polymerase and various synthetic DNA oligomers as templates (1265 b), we have obtained efficient synthesis of RNA transcripts without the need for either primer or promoter. Gel analysis of transcripts made from templates of known size demonstrated a predominant single species, together with some minor bands. For a given template the major band had the same 5'-nucleotide as predicted from the 3'-nucleotide of the template. This synthesis procedure makes it possible to efficiently and conveniently make labeled or unlabeled RNA from synthetic DNA oligonucleotides.
