24 Mar 1999 | | Subject: | Soft Condensed Matter; Biological Physics; Biomolecules | cond-mat.soft physics.bio-ph q-bio.BM | | Abstract: | We examine the conformations of a model for a short segment of closed DNA. The molecule is represented as a cylindrically symmetric elastic rod with a constraint corresponding to a specification of the linking number. We obtain analytic expressions leading to the spatial configuration of a family of solutions representing distortions that interpolate between the circular form of DNA and a figure-eight form that represents the onset of interwinding. We are also able to generate knotted loops. We suggest ways to use our approach to produce other configurations relevant to studies of DNA structure. The stability of the distorted configurations is assessed, along with the effects of fluctuations on the free energy of the various configurations. | | Source: | arXiv, cond-mat/9903364 | | Services: | Forum | Review | PDF | Favorites | |
