#Unit 2. Cellular Organization

When all the kinetochores have properly attached to spindle microtubules, APC/CCdc20 directs ubiquitinylation of securin and mitotic cyclins

#Unit 2. Cellular Organization

APC/CCdc20 is inhibited by a checkpoint pathway that ensures that anaphase is not initiated until all chromosomes have achieved proper attachment to the mitotic apparatus.

Following securin degradation and a decrease in mitotic CDK activity, separase cleaves the Scc1 subunit, breaking the cohesin circles.
