Although pathways for assembly of RNA polymerase (Pol) II tran-
scription preinitiation complexes (PICs) have been well established
in vitro, relatively little is known about the dynamic behavior of Pol
II general transcription factors in vivo. In vitro, a subset of Pol II
factors facilitates reinitiation by remaining very stably bound to
the promoter. This behavior contrasts markedly with the highly
dynamic behavior of RNA Pol I transcription complexes in vivo,
