WebDec 20, 2024 · The long-standing paradigm of chromosome organization — variants of which are found in all textbooks — holds that the 10-nm chromatin fiber continuously folds, twists, and coils into increasingly more condensed structures until chromosomal-level compaction is achieved [12–15].Central to this view is folding of the 10-nm fiber into a … WebApr 16, 2014 · Old and novel views of chromatin structure. A long DNA molecule with a diameter of ∼2 nm is wrapped around a core histone octamer and forms a nucleosome with a diameter of 11 nm (Alberts et al. 2007).The nucleosome has long been assumed to fold into 30-nm chromatin fibers (left) and subsequently into the higher order organization …
WebNov 24, 1998 · Higher-order chromatin folding is critically dependent on the N termini of the core histones (22–24, 41, 59).
