In higher organisms, all cells share the same genome, but every cell expresses only a limited and specific set of genes that defines the cell type. During cell division, not only the genome, but also the cell type is inherited by the daughter cells.

Using magnetic tweezers to investigate the mechanical response of single chromatin fibers, we show that fibers submitted to large positive torsion transiently trap positive turns, at a rate of one turn per nucleosome. A comparison with the response o

Structural plasticity of single chromatin fibers revealed by torsional manipulation

Autor: Bancaud, Aurelien, Silva, Natalia Conde e, Barbi, Maria, Wagner, Gaudeline, Allemand, Jean-Francois, Mozziconacci, Julien, Lavelle, Christophe, Croquette, Vincent, Victor, Jean-Marc, Prunell, Ariel, Viovy, Jean-Louis

Magnetic tweezers are used to study the mechanical response under torsion of single nucleosome arrays reconstituted on tandem repeats of 5S positioning sequences. Regular arrays are extremely resilient and can reversibly accommodate a large amount of

A Physical Model for the Condensation and Decondensation of Eukaryotic Chromosomes

Autor: Mozziconacci, Julien, Lavelle, Christophe, Barbi, Maria, Lesne, Annick, Victor, Jean-Marc

Publikováno v: FEBS Letters 580 (2006) 368-372

During the eukaryotic cell cycle, chromatin undergoes several conformational changes, which are believed to play key roles in gene expression regulation during interphase, and in genome replication and division during mitosis. In this paper, we propo
