Final answer:
The binding of M-cdk and Cyclin causes the activation of the M-cdk/cyclin complex, which phosphorylates other proteins and advances the cell to the next phase of the cell cycle.
Step-by-step explanation:
The binding of M-cdk and Cyclin causes the activation of the M-cdk/cyclin complex, which plays a crucial role in regulating the cell cycle. When Cyclin is bound to M-cdk, the complex becomes fully active and phosphorylates other proteins involved in advancing the cell to the next phase of the cell cycle. This activation process changes the shape of the proteins, activating them and allowing the cell cycle to progress through the checkpoints.
