Distance populations for DNA end-to-end spread. The canonical system exists in two states: one centered around 67 Å (compact) and one centered around 71 Å (open). Although the L1-mutant samples both states, the amount of time spent in the open state is drastically reduced. The macroH2A and H2A.Z nucleosomes exist only in the compact state. Fits are represented in dotted lines. To see this figure in color, go online.
