Following statements are regarding to the protein phosphatase Cdc14 function in budding yeast.

A. In budding yeast, the protein phosphatase Cdc14 throws the switch between two mutually antagonistic states during anaphase.

B. Cdc14 is kept inactive during most of the cell cycle, but is activated during anaphase by a GTPase signaling pathway known as the mitotic exit network.

C. Mitotic exit network is unresponsive to spindle position and becomes active in anaphase.

D. Cdc14 phosphatase activated by the activation of protein kinase cascade.

E. Cdc14 dephosphorylates APC/CCdh1 and Sic1 to promote mitotic cyclin degradation

and mitotic CDK inactivation, respectively. This process leads to exit from mitosis.
