Exotic Properties of a Single DNA Chain
Individual giant DNA chains show a discrete conformational change, the folding phase transition, between an elongated coil state and a folded compact state under existence of multivalent cations, polymer chains, multivalent anions, and alcohols on the level of a single molecular chain. The stiffness of a polymer chain is essential for the transition. The single DNA chain also expresses a rhythmic conformational change between the coil and folded states under a thermodynamically open condition
