Regulation of the dynamics of nucleosomes and chromatin fibers. The unwrapping dynamics of nucleosomes, which facilitates the access of transcription factors, and the inter-nucleosome stacking dynamics, along with various factors that regulate the dynamics, which factors include ion concentrations, PTM on histones, and nucleosome spacing, are shown in schematic.
