Histone phase separation

Webb14 juli 2024 · The form of phase separation that yields multiple droplets or condensates – a process known as emulsification – is thought to arise from the active production and degradation of macromolecules ( Wurtz and Lee, 2024 ). However, there have also been reports of emulsification happening in the absence of these active mechanisms. WebbThe histones form a disk-shaped complex called a nucleosome, which contains two complete turns of double-stranded DNA wrapped around its surface. These non-specific interactions are formed through basic residues in the histones, making ionic bonds to the acidic sugar-phosphate backbone of the DNA, and are thus largely independent of the …
