Fig. 6: Effects of DNA unwrapping on chromatin fiber elasticity and bendability.
From: Histone dynamics mediate DNA unwrapping and sliding in nucleosomes
a End-to-end distance distribution in a simulated conformational ensemble of six NCPs connected by straight 15 bp linker DNA segments. Odd and even NCPs are colored in yellow and red, respectively, to highlight the fiber’s “two-start” structure. b Decay of orientational correlations along the nucleosome fibers due to DNA unwrapping. Persistence length estimates are shown on the plot. Below the plot, two different conformations of the fiber are shown.
