WebbIn transcription initiation, RNA polymerase (RNAP), together with at least one transcription initiation factor, binds to promoter DNA to yield an RNAP-promoter closed complex (RPc) and then unwinds ~12 bp of promoter DNA to form a “transcription bubble” and yield an RNAP-promoter open complex (RPo) (1). RPo is the critical, catalytically com- WebbAlthough transcription proceeds by the same fundamental mechanizations in all cells, it is considerably more complex in eukaryotic cells less in bacteria.
