Stathmin is phosphorylated by cyclin dependent kinases in response to extracellular signals such as growth factors. To further understand the role of phosphorylation in stathmin function, you decide to treat cells with growth factors in the presence or absence of phosphatase and observe microtubule dynamics. Based on the known function of stathmin, and phosphorylation of stathmin, how would you expect phosphatase treatment to affect microtubule dynamics? OA. Decreased frequency of catastrophe in the presence of phosphatase, compared to untreated control OB. Increased frequency of catastrophe in the presence of phosphatase, compared to untreated control OC. Rapid microtubule polymerization in the presence of phosphatase, compared to untreated control OD. Catastrophe frequency is the same in phosphatase treated and control cells
