We have analyzed the fate of the RNA polymerase II (RNAPII) general transcription factors during the transition from initiation to elongation using multiple approaches. We demonstrate that all of the basal factors coexist in mature initiation complexes but that following nucleotide addition, this complex becomes disrupted. During this transition, TFIID remains promoter-bound whereas TFIIB, TFIIE, TFIIF, and TFIIH are released. Upon release, TFIIB reassociates with TFIID, reforming the RNAPII docking site, the DB complex. TFIIE is released before formation of the tenth phosphodiester bond. This precedes TFIIH release, which occurrs after the transcription complex reaches +30. TFIIF is unique in that it is the only basal factor detected in the RNAPII elongation complex. Following its release from the initiation complex, TFIIF has the ability to reassociate with a stalled RNAPII.
