a Experimental data from [20] for T7 RNAP where the fluorescence intensity corresponds to the rate of transcript initiation in the absence of gyrase and the presence of Topo I. b The cumulative sum (red line) of the data in a corresponding to the total number of mRNA transcripts produced through time. Also shown are the times of average transcription events (green triangles) determined from the original data, see text. c The time between average transcription events. d The initiation rate by transcription event number (green triangles) and a linear fit (dashed line)
