FIG. 4.
Histone H3 deposition tracks with clearance of Pol II. Galactose-grown cells containing GAL1-YLR454 were shifted into glucose medium for the indicated time (in minutes) and examined for (A) Pol II density (8-min time point arbitrarily set to 1) and (B) H3 density (0-min time point arbitrarily set to 1) at the indicated regions within the 8-kb YLR454 coding region. Standard deviations (not shown) were generally less than 15% of the means. ORF, open reading frame.
