What is meant by “global RNA polymerase occupancy”? I read the following in a paper > It provides base-pair resolution and strand-specific information of **global RNA polymerase** occupancy. CDK13 cooperates with CDK12 to control **global RNA polymerase II** processivity What does this mean?

In context of the PRO-seq method, "global" can be substituted for "genome-wide". Note that use of the term _global_ is a call-back to the methodological predecessor of PRO-seq, which was called **global run-on sequencing** (GRO-seq).
