FIG 3.

RDT at position 1,183, about 10 nucleotides downstream from the 3′ end of the galE mRNA. (A) 3′ RACE assay of the 3′ ends of the galE mRNA in the DH1200 mutant in the presence of increasing BCM concentrations. (B) 3′ RACE assay of the 3′ ends of transcripts generated by in vitro transcription in the presence of the indicated concentrations of Rho protein (see the text). The 3′ end at position 1,183 in lane 2 might have been generated by Rho contamination in the RNA polymerase preparation used in the in vitro transcription reaction.
