The recent contributions on chromatid segregation at the metaphase/anaphase transition demonstrate two distinct pathways in budding yeast. While segregation of most of the genome is a direct consequence of cohesin cleavage by separase, rDNA segregation requires a novel pathway involving Cdc14 phosphatase activation. This activation induces targeting of condensin to rDNA which in association with Aurora B kinase modulates rDNA compaction during anaphase. The resolution of rDNA sequences occurs after this step.
