Figure 1: Illustration of the residue-level coarse-grained explicit-ion model for chromatin simulations.

Figure 1:

The left panel presents a snapshot for the simulation box of a 147-bp nucleosome in a solution of 100 mM NaCl and 0.5 mM MgCl2. The nucleosomal DNA and histone proteins are colored in red and white, respectively. The Zoom-in on the right highlights the condensation of ions around the nucleosome, with Na+ in cyan and Mg2+ in yellow. Negative residues of the histone proteins are colored in pink.
