Gradual recruitment of Pol II to the Hsp70 loci in vivo. Additional Pol II is recruited to Hsp70 loci (white doublet) at ~2 min post-HS (third panel) and accumulates until ~5-min post-HS (seventh panel). After 5 min of HS, Pol II reaches maximal levels and remains high for the duration of the experiment.
