Topological diversity of chromatin fibers: Interplay between nucleosome repeat length, DNA linking number and the level of transcription
The spatial organization of nucleosomes in 30-nm fibers remains unknown in detail. To tackle this problem, we analyzed all stereochemically possible configurations of two-start chromatin fibers with DNA linkers L = 10-70 bp (nucleosome repeat length NRL = 157-217 bp). In our model, the energy of a f...
