Extended Data Fig. 1:

Fragment enrichment is correlated with termination efficiency. Related to Fig. 1. Cumulative distribution of enrichment in the absence of BCM (Rho active) for fragments containing an annotated intrinsic terminator, separated by termination efficiency³² (Methods). Fragments with more than 100 reads in the pre-selection sample are included. n indicates number of fragments in each distribution. Below det., below detection limit (Methods).
