Dynamical Intermediates in the Collapse of Semiflexible Polymers in Poor Solvents

Schnurr, B; MacKintosh, F; Williams, David

Description

We investigate, by a Brownian Dynamics (BD) simulation, the collapse of a single, semiflexible or stiff polymer in solution, in the presence of short-range, attractive interactions. In contrast to the mechanism for flexible chains, our results suggest that the collapse occurs via a series of long-lived, metastable intermediates. These intermediates form a well-defined, hierarchical family of conformations. Experiments with DNA condensation have shown similar shapes, which were described as...[Show more]
