Unwinding Dynamics of a Helically Wrapped Polymer

Jean-Charles Walter, Marco Baiesi, Enrico Carlon +1

We study the rotational dynamics of a flexible polymer initially wrapped around a rigid rod and unwinding from it. This dynamics is of interest in several problems in biology and c…

Multi-plectoneme phase of double-stranded DNA under torsion

Marc Emanuel, Giovanni Lanzani, Helmut Schiessel

We use the worm-like chain model to study supercoiling of DNA under tension and torque. The model reproduces experimental data for a broad range of forces, salt concentrations and…

Multi-plectoneme phase of double-stranded DNA under torsion

Marc Emanuel, Giovanni Lanzani, Helmut Schiessel

We use the worm-like chain model to study supercoiling of DNA under tension and torque. The model reproduces experimental data for a much broader range of forces, salt concentratio…

Stochastic model for nucleosome sliding in the presence of DNA ligands

Laleh Mollazadeh-Beidokhti, Julien Deseigne, David Lacoste +2

Heat-induced mobility of nucleosomes along DNA is an experimentally well-studied phenomenon. A recent experiment shows that the repositioning is modified in the presence of minor-g…

Nucleosome shape dictates chromatin-fiber structure

Martin Depken, Helmut Schiessel

Apart from being the gateway for all access to the eukaryotic genome, chromatin has in recent years been identified as carrying an epigenetic code regulating transcriptional activi…

Semi-classical buckling of stiff polymers

Marc Emanuel, Hervé Mohrbach, Mehmet Sayar +2

A quantitative theory of the buckling of a worm like chain based on a semi-classical approximation of the partition function is presented. The contribution of thermal fluctuations…
