SEX CHROMOSOME DEPENDENT SEGREGATION FREQUENCY IN <i>DROSOPHILA MELANOGASTER</i>

Chromosome Segregation in Drosophila Virilis Males with Multiple Sex Chromosomes.

NE of the many puzzling aspects of chromosome mechanics is the process of 0 pairing of homologous chromosomes and their disjunction a t the first meiotic division. A genetic indication of the intimacy of pairing is the amount of exchange taking place between homologous chromosomes. Where more than two chromosomes share homologies, as in translocation heterozygotes, the correlation between excha...

Role of chromosome segregation genes in BRCA1-dependent lethality.

Chromosome segregation in Eubacteria.

It is now clear that bacterial chromosomes rapidly separate in a manner independent of cell elongation, suggesting the existence of a mitotic apparatus in bacteria. Recent studies of bacterial cells reveal filamentous structures similar to the eukaryotic cytoskeleton, proteins that mediate polar chromosome anchoring during Bacillus subtilis sporulation, and SMC interacting proteins that are inv...

Karyotype and Sex-Chromosome Polymorphism in Nesokia indica, from Iran

ISWI is a RanGTP-dependent MAP required for chromosome segregation

Production of RanGTP around chromosomes induces spindle assembly by activating nuclear localization signal (NLS)-containing factors. Here, we show that the NLS protein ISWI, a known chromatin-remodeling ATPase, is a RanGTP-dependent microtubule (MT)-associated protein. Recombinant ISWI induces MT nucleation, stabilization, and bundling in vitro. In Xenopus culture cells and egg extract, ISWI lo...
