a Metagene analyses and heat maps of ChIP-seq data (n = 20,130 genes) for total Pol II, pSer2, total Spt5, and Spt5-pThr806, as indicated (n = 2 biological replicates). b Individual gene tracks of Pol II, Pol II-pSer2, Spt5, Spt5-pSer666, and Spt5-pThr806 (y-axis scale indicated by number at top left of each track). c Metagene analysis of pThr806:Spt5 and pSer2:Pol II ratios (n = 20,130 genes).
