Web2.19.3.2 Mechanisms of Chromatin Remodeling. The wide variety of chromatin remodeling complexes that exist allow for a number of different mechanisms to remodel chromatin. Remodelers can slide nucleosomes, eject histone octamers, remove H2A-H2B dimers, and replace dimers (Cairns 2007 ). These actions require breakage of all 14 …
WebJan 3, 2024 · Chromosomes and chromatin are a uniquely eukaryotic association of DNA with more or less protein. Bacterial DNA (and prokaryotic DNA generally) is relatively ‘naked’ – not visibly associated with protein. The electron micrograph of an interphase cell (below) reveals that the chromatin can itself exist in various states of condensation. WebAs a result, chromatin can be packaged into a much smaller volume than DNA alone. Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, …
