WebAbstract. Features of higher-order chromatin organization-such as A/B compartments, topologically associating domains and chromatin loops-are temporarily disrupted during mitosis 1,2. Because these structures are thought to influence gene regulation, it is important to understand how they are re-established after mitosis. WebApr 2, 2013 · Mitosis is accompanied by dramatic changes in chromatin organization and nuclear architecture. Transcription halts globally and most sequence-specific transcription factors and co-factors are ejected from mitotic chromatin.
