1-Kinase cascade proteins need to act sequentially in order to be effective. How does the cell help to ensure that these reactions take place in the correct order, despite occurring in a large volume of reaction space in the cytoplasm? What are the advantage(s) and disadvantage to this method of reaction organization?
2-A new chemical is derived that hinders the formation of MPF, thereby inhibiting the formation of this kinase-cyclin complex. Identify which checkpoint within eukaryotic cell cycle would be affected by this chemical's inhibitory action and explain the result.?
