The schematic diagram to the right shows the activation of M-Cdk in mitosis. Indicate what protein (or protein function) corresponds to those indicated as A, B, C, and D in the diagram. Briefly explain the importance of each protein function. Briefly describe how sister chromatids are able to separate during the metaphase-to-anaphase transition.

Akaike Y(1), Chibazakura T(1). Author information: (1)Department of Bioscience, Tokyo University of Agriculture, Tokyo, Japan. Cyclin A-cyclin dependent kinase (CDK) activity is regulated by cyclin A proteolysis and CDK inhibitors (CKIs) during M and G1 phases. Cdc25B and Cdc25C are primarily required for entry into mitosis. Cdc25B is responsible for the initial activation of CDK1/cyclin B at the centrosome during the G2/M transition, which is then followed by a complete activation of CDK1/cyclin B complexes by Cdc25C in the nucleus at the onset of mitosis. CDK activation initiates a positive feedback loop that further increases CDK activity, and this commits the cell to division by inducing genome-wide transcriptional changes.

The activation of M-Cdk begins abruptly mainly because: A. M cyclin increases abruptly. MPF, as we have noted, is an M-Cdk. That is, it is a cyclin-dependent protein kinase. As such, it catalyzes the transfer of a phosphate group from ATP to target proteins. Phosphorylation can activate the target protein.

What does the phosphorylation of Cdc25 by M-Cdk do? A It inactivates Cdc25, preventing further activation of M-Cdk. B It activates Cdc25, which inactivates M-Cdk. C It activates Cdc25, which in turn activates more M-Cdk. D It inactivates Cdc25, which promotes activation of more M-Cdk. E It activates Cdc25, allowing the cell to exit mitosis.
