Constraints, Histones, and the 30 Nanometer Spiral
Roya Zandi, Joseph Rudnick
We investigate the mechanical stability of a segment of DNA wrapped around a histone in the nucleosome configuration. The assumption underlying this investigation is that the prope…
Radial Distribution Function of Rodlike Polyelectrolytes
Roya Zandi, Joseph Rudnick, Ramin Golestanian
We study the effect of electrostatic interactions on the distribution function of the end-to-end distance of a single polyelectrolyte chain in a rodlike configuration. We investiga…
Organized condensation of worm-like chains
H. Schiessel, J. Rudnick, R. Bruinsma +1
We present results relevant to the equilibrium organization of DNA strands of arbitrary length interacting with a spherical organizing center, suggestive of DNA-histone complexatio…
Conformations of closed DNA
Boris Fain, Joseph Rudnick
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…
DNA-Protein Cooperative Binding through Long-Range Elastic Coupling
Joseph Rudnick, Robijn Bruinsma
Cooperativity plays an important role in the action of proteins bound to DNA. A simple, mechanical mechanism for cooperativity, in the form of a tension-mediated interaction betwee…
