Liquid-like histone H1 'glues' nucleosomes, reshaping how DNA compacts
DNA inside the nucleus is not packed as a rigid regular fiber—linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still support essential genome functions.
