Figure 1. Structure of the nucleosome core particle.

Figure 1

(A). Schematic representation of the NCP with histone tails stretched out. The net positive charge of the globular (core) part of the histone octamer (Z = +52e) and of the histone tails is shown. (B) The nucleosome crystal structure at 1.9 Å resolution (pdb 1KX5 [2]). (C) Side view of the NCP to highlight its wedge shape.
