GR binding at the MMTV tandem array. The MMTV tandem array (bright green puncta in a) is typically associated with a distinct cluster of polymerase II puncta (b,c). This cluster of polymerase II at the array can also be discerned in live cells (white box in d), and used to define a transcriptionally active zone at the array (yellow outline in the inset). (e) A much higher fraction of molecules with longer dwell times are found at the array compared to randomly selected transcription sites. Scale bars 1 µm.
