Term Detail
GO term:chromosome separation
Synonym: chromatid release
Synonym: rDNA separation
GO id:GO:0051304
Alternate id: GO:0034500
Definition:The cell cycle process in which paired chromosomes are detached from each other. Chromosome separation begins with the release of cohesin complexes from chromosomes; in budding yeast, this includes the cleavage of cohesin complexes along the chromosome arms, followed by the separation of the centromeric regions. Chromosome separation also includes formation of chromatid axes mediated by condensins, and ends with the disentangling of inter-sister catenation catalyzed by topoisomerase II (topo II).
Number of paths to term: 6
