Comments "By quantifying these fractions, Bakshi et al. (primary source) obtain a global picture of the activities of RNAPs in the cell. Only approximately one-half of the RNAPs are found engaged in active transcription, but a large fraction is bound to DNA, either specifically or nonspecifically (82%)."
