Figure 5

The writhing-induced transition occurring in the chromatin fiber with the linker L = 20 bp. Note the different mutual positioning of linkers in the fibers with ρ = –130°, –120°, and –110° (A, B, and C, respectively). (A) The two bottom linkers shown in blue are positioned above the linker shown in orange (solid blue arrow). (B) Overcrossing (intersection) of the blue and orange DNA linkers (dotted-line blue arrow). (C) The two bottom blue linkers are positioned below the orange linker (dash-and-dot blue arrow).
