How confinement or a physical constraint modifies polymer chains is not only a classical
problem in polymer physics but also relevant in a variety of contexts such as single-molecule …

Replicating bacterial chromosomes continuously demix from each other and segregate
within a compact volume inside the cell called the nucleoid. Although many proteins …

The unconstrained genomic DNA of bacteria forms a coil, whose volume exceeds 1000
times the volume of the cell. Since prokaryotes lack a membrane-bound nucleus, in sharp …

A microscopic statistical theory of a symmetrical polyelectrolyte complex (PEC) is developed.
PEC is shown to form a polymer globule. The equilibrium density of PEC, the width of a PEC …

Experiments show that macromolecular crowding modestly reduces the size of intrinsically
disordered proteins even at a volume fraction (ϕ) similar to that in the cytosol, whereas DNA …

In thermophoresis, with the fluid at rest, suspensions move along a gradient of temperature.
In an aqueous solution, a PEG polymer suspension is depleted from the hot region and …

DNA compaction in a bacterial cell is in part carried out by entropic (depletion) forces
induced by “free” proteins or crowding particles in the cytoplasm. Indeed, recent in vitro …

We studied theoretically the behavior of a collapsed persistent macromolecule in poor
solvent as a model of collapse transition of single double‐stranded DNA chain, and …

Whereas many physicochemical investigations have shown that among monovalent cations
Na+ ion possesses minimal potential for DNA binding, biological assays have shown that …

The formation and properties of dispersions of double stranded natural and synthetic nucleic
acids are described. Evidence is given for the liquid-crystalline state of the nucleic acid …
