Figure 1

Schematic diagram of the effects of histone acetylation and deacetylation on chromatin structure (red spheres on stalks represent acetyl groups linked to histones). Gold tone depicts a more “open” structure for acetylated chromatin; this open structure could conceivably be manifested as changes in nucleosome occupancy (a), changes in the nucleosome conformation (b), changes in internucleosome interactions (c), and/or changes in higher-order chromatin packaging and structure (d).
