abstract::Three single-stranded RNA transcripts synthesized in vitro by a virion-associated RNA polymerase of bacteriophage phi 6 were sequenced at their 5'- and 3'-termini. The sequences agreed with those of the + strands of the 3 double-stranded RNA segments [FEBS Lett. (1982) 141,111-115]. The results show that the transcrip...
