Chromosome oscillations in mitosis.
The motion and positioning of chromosomes during eukaryotic cell division is investigated theoretically. We perform a self-contained analysis where the motion of mono-oriented chromosomes results from the competition between the kinetochore and chromokinesin motors on the chromosome arms. We show that the interplay between the asterlike morphology of the mitotic spindle and the collective dynam...
متن کاملChromosome Dynamics during Mitosis.
The primary goal of mitosis is to partition duplicated chromosomes into daughter cells. Eukaryotic chromosomes are equipped with two distinct classes of intrinsic machineries, cohesin and condensins, that ensure their faithful segregation during mitosis. Cohesin holds sister chromatids together immediately after their synthesis during S phase until the establishment of bipolar attachments to th...

متن کاملChromosome cohesion in mitosis and meiosis.
During mitosis and meiosis sister chromatids are held together by protein complexes. This cohesion is important not only for pairwise alignment of chromosomes on the mitotic spindle but also for the generation of tension across centromeres – it counteracts the pulling force of spindle microtubules, which ensures the bipolar attachment of chromosomes. Chromosome cohesion thus enables accurate ch...
متن کاملDynamics of chromosome compaction during mitosis.
We have quantitatively studied the space-time dynamics of mitotic chromosome compaction in cultured amphibian cells. After collecting digital phase-contrast images we have done digital image analysis to study spatial correlations in density. We find a characteristic distance at which the strongest correlations occur, which provides a quantitative measure of the size of patches of dense chromati...
