The Spindle's Model Behavior

submitted by: JCB
Dynamic microtubules assemble into a steady state bipolar spindle structure but precisely how this is achieved is unclear. Loughlin et al. develop a computational model that predicts how a few key activities organize microtubules in Xenopus meiotic spindles. This biosights episode presents the paper by Loughlin et al. from the December 27, 2010 issue of The Journal of Cell Biology, and includes an interview with author François Nédélec (EMBL, Heidelberg, Germany). Produced by Caitlin...

Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcriptional Perturbation

submitted by: akshayb
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes....
