Chromatin is partitioned on multiple length scales into subcompartments that differ from each other with respect to their molecular composition and biological function. It is a key …
The human genome folds to create thousands of intervals, called" contact domains," that exhibit enhanced contact frequency within themselves." Loop domains" form because of …
Liquid–liquid phase separation (LLPS) is an important mechanism that helps explain the membraneless compartmentalization of the nucleus. Because chromatin compaction and …
Biomolecular simulation is increasingly central to understanding and designing biological molecules and their interactions. Detailed, physics‐based simulation methods are …

The intricacies of the 3D hierarchical organization of the genome have been approached by many creative modeling studies. The specific model/simulation technique combination …
Remodelling of chromatin architecture is known to regulate gene expression and has been well characterized in cell lineage development but less so in response to cell perturbation …
Eukaryotic cells must fit meters of DNA into micron-sized cell nuclei and, at the same time, control and modulate the access to the genetic material. The necessary amount of DNA …
