DNA sequences used in transcription. Only the sense strands (top strands) are shown. The T7 promoter sequences are underlined and the initiating nucleotides are in bold. The grouped pair sequences are the same except for the promoter sequences and the initiating nucleotides. CA0 is Escherichia coli tRNAAla, and CA2 is the GC4-69 mutant of CA0 described previously (4). 35n is a RNA sequence used previously in our work (7,8).
