Method	To determine whether the dynamic behavior of the Pol II machinery in vivo is fundamentally different from that of Pol I and whether the static behavior of Pol II factors in vitro fully recapitulates their behavior in vivo, researchers used fluorescence recovery after photobleaching (FRAP). Signal noise resulting from the small size of the bleach spot combined with the relatively faint intranuclear YFP signals was overcome by collection of FRAP data from ˜30–100 individual cells.
