Figure 4.

(a) Snapshots of simulation results of 50 nucleosomes and 100 nucleosomes in the absence and presence of NHPs (left to right) for ε = 0.15. Neighboring nucleosomes (odd, even) are shown in different colors so that the regular/irregular organization is more visible to the eye. (b) Shown is the packing density and fiber width on varying chromatin fiber length in the absence and presence of NHPs for different LJ interaction strengths (ε). Packing densities and fiber widths increase as we increase the chromatin length. Colors red, green, and blue represent different LJ interaction strengths ε = 0.1, 0.15, and 0.2 kcal/mol, respectively.
