WebMay 4, 2024 · Chromatin is a complex, linear macromolecule comprising DNA and histone proteins which in eukaryotic cells, is localized in the nucleus where it is solubilized in water, salts, and other small molecules ( Cooper and Hausman, 2000; Phillips et al., 2012 ). In many studies, chromatin organization in interphase is homogeneous on the nuclear scale. WebApr 7, 2024 · A rapidly evolving understanding of phase separation in the biological and physical sciences has led to the redefining of virus-engineered replication compartments in many viruses with RNA genomes. Condensation of viral, host and genomic and subgenomic RNAs can take place to evade the innate immunity response and to help viral replication. …
