Fig. 4: Internal organization of the OLTN.

a Schematic representation of the DNA regions occupied by the proximal hexasome, the central hexasome, and the distal octasome in the OLTN structure. b Illustration of the OLTN structure. The H2A–H2B complexes are colored green, blue, and magenta. The H3–H4 complexes are gray. c and d Close-up views of the hexasome–hexasome interface (c) and the hexasome–octasome interface (d).
