Condensins are molecular motors that compact DNA via linear translocation. In C. elegans, the X-chromosome harbors a specialized condensin that participates in dosage compensation (DC). Condensin DC is recruited to and spreads from a small number of

Chromatin is a very long DNA–protein complex that controls the expression and inheritance of the genetic information. Chromatin is stored within the nucleus in interphase and further compacted into chromosomes during mitosis. This process, known as

Background Most data concerning chromosome organization have been acquired from studies of a small number of model organisms, the majority of which are mammals. In plants with large genomes, the chromosomes are significantly larger than the animal ch

The size of mitotic chromosomes is coordinated with cell size. Through an RNAi screen in Caenorhabditis elegans, Ladouceur et al. identify CENP-A and topo-II as factors affecting chromosome length. Quantitative analyses of protein dynamics suggest th

Incorporating each set of daughter chromosomes into a single nucleus at the end of mitosis is essential for genome stability. In a recent Cell paper, Samwer et al. (2017) show that by non-covalently crosslinking DNA, BAF promotes chromosome coalescen

How eukaryotic genomes are packaged into compact cylindrical chromosomes in preparation for cell divisions has remained one of the major unsolved questions of cell biology. Novel approaches to study the topology of DNA helices inside the nuclei of in

One essential role of the first meiotic division is to reduce chromosome number by half. Although this is normally accomplished by segregating homologous chromosomes from each other, it is possible for a genome to have one or more chromosomes that la

Sex chromosomes have evolved many times from morphologically identical autosome pairs, most often presenting several recombination suppression events, followed by accumulation of repetitive DNA sequences. In Orthoptera, most species have an X0♂ sex

Chromatin structure can affect the organization and maintenance of chromosomes. Recent discoveries in several filamentous fungi suggest mechanisms for the clustering and co-regulation of secondary metabolite genes or pathogenicity islands. An extreme
