(A) Twelve-core chromatin conformation at 5,000,000 MC steps at 0.15 M NaCl salt with its internucleosome interaction intensity I(k) showing a dominant zigzag feature (peak at k = 2). (B) Shielding charges around the four chromatin components of chromatin structure in panel A. The net (solid line), Na⁺ (dash-dotted line), and Cl^– (dashed line) shielding charges are plotted versus nucleosome core position. (Color figure reproduced in Fig. S5.)
