The 30nm chromatin fiber: As dense as it gets — •Martin Depken1 and Helmut Schiessel2 — 1Max-Planck-Institut für Physik komplexer Systeme, Dresden, Germany — 2Instituut-Lorentz for Theoretical Physics, Leiden, The Netherlands
We address the problem of the structure of the 30nm chromatin fiber. By considering the packing of nucleosomes at the periphery of the fiber, together with their connections through the DNA linker backbone, we characterise the possible dense configurations without having to assume anything about the bending of the linker backbone. This results in a set of dense fiber configurations with properties that can be compared with experimental findings to determine possible structures.
