The sister chromosomes separate and move toward the poles, and the spindle elongates to spread the poles.
Research published in 2002 suggests that checkpoint proteins such as Mad2, dynactin, and CENP-E do not need to be depleted before this can begin, as previously thought. However, Cyclin A must be fully consumed and Cdc20 must be free of the presence of antibodies, or this will not occur. Its first part is the separation of tetrads, while the second part creates individual chromatids, now randomized through crossing over. The sister chromosomes separate and move toward the poles, and the spindle elongates to spread the poles. For ten points, name this phase of mitosis between metaphase and telophase.
