The drug Taxol, or Paclitaxel, is used to treat patients with a variety of cancers, including breast, lung and ovarian cancers.  The drug works by stabilizing microtubules, and preventing their disassembly.  The goal of the drug is to prevent dividing cells from being able to complete mitosis.  As a result, cancerous cells can no longer divide.  In a cell treated with Taxol, at what stage of mitosis will the cells arrest?

A. Prior to metaphase B. Telophase C. Anaphase D. Cytokinesis
