There are two approaches to describing DNA-ions interactions. The physical approach is an analysis of electrostatic interactions between ions and charges on the DNA molecule. The coordination chemistry approach is a search for modes of…
Phase separation in biomolecular mixtures can result from multiple physical interactions, which may act either complementarily or antagonistically. In the case of protein-nucleic acid mixtures, charge plays a key role but can have…
