The Lengths of Microtubules in Various Stages of Mitosis Depend

question 47

Essay

The lengths of microtubules in various stages of mitosis depend on the balance between the activities of proteins that destabilize microtubules, and microtubule-associated proteins that stabilize them.If you created cells with an increased number of proteins that destabilize molecules, do you predict the length of the mitotic spindle will be longer, shorter, or unchanged, relative to the corresponding stage of mitosis in wild-type cells? What do you predict for a cell with increased numbers of microtubule stabilizing proteins? Explain your reasoning.
