A)Cdc25 dephosphorylation of Wee1 activates the kinase, promoting the G2/M transition. B)Phosphorylation of mitotic Cdk by the inhibitory kinase (Wee1) makes the Cdk inactive. C)Inhibiting the Cdc25 phosphatase will delay the G2/M transition. D)The activating phosphatase (Cdc25) removes the phosphates from mitotic Cdk that were added by Wee1, so that M-Cdk will be active.
