Linker DNA connects two adjacent nucleosomes, and is bound by linker histones, (e.g. H1) that organize the 10-nm nucleosomal array into a 30-nm fiber. This 30-nm fiber is the predominant structure of interphase chromatin, but permits low accessibility and Webb7 mars 2024 · Histones associated with the DNA prevent them from being intertwined and damaged.
