Chromatine organisation
WebAug 17, 2024 · Background Biomolecular condensates have been implicated in multiple cellular processes. However, the global role played by condensates in 3D chromatin organization remains unclear. At present, 1,6-hexanediol (1,6-HD) is the only available tool to globally disrupt condensates, yet the conditions of 1,6-HD vary considerably between … WebThe dynamic organization of chromatin structure thereby influences, potentially, all functions of the genome. The fundamental unit of chromatin, termed the nucleosome, is composed of DNA and histone proteins. This structure provides the first level of compaction of DNA into the nucleus. Nucleosomes are regularly spaced along the genome to form ...
