Figure S8. Composite profile of all histone marks at active genes.
Composite enrichment profiles for genes called present for mRNA transcript using Affymetrix data (Sato et al., 2003; Abeyta et al., 2004). The start and direction of transcription of the average gene is noted by arrow. Experiments included are initiating RNA polymerase II (8WG16, red solid), elongating RNA polymerase II (4H8, red dashed), H3 globular (grey), H3K4me3 (blue), H3K9/14Ac (green), and H3K36me3 (orange).
