#Unit 2. Cellular Organization

If chromosome segregation occurs properly, extension of the spindle microtubules inserts the daughter SPB into the bud, causing Tem1 to be activated by an unknown mechanism.

#Unit 2. Cellular Organization

Tem1-GTP activates a protein kinase cascade, which promotes the release of active Cdc14 from the nucleolus and exit from mitosis.
