Abstract

Certain biopolymers, such as DNA, have a multi-stranded chain structure and exhibit characteristic tertiary structures due to twisting or anisotropic rigidity. We studied the effect of chain twisting and anisotropic rigidity on the behavior of a circular double-stranded polymer chain using a Monte Carlo simulation. We found that there are two regimes for the chain conformation, depending on its twisting. In the first regime, with weak twisting, a chain behaves like a coiled linear chain. In the second regime, the chain shows scaling dependencies characterized by supercoiled structures.
