Mitosis: aurora gives chromosomes a healthy stretch.
Attachment of sister chromatids to microtubules from opposite spindle poles--bi-orientation--generates tension at the kinetochores. The Ipl1/Aurora B kinase responds to the absence of tension at mono-oriented chromosomes and promotes microtubule turnover and spindle checkpoint activation until a stable bi-oriented attachment is achieved.
