The step preceding it is ended by inactivation of cyclin dependent kinases, and the kinetochore fibers become shorter during this step. Chromatid pairs separate into identical chromosomes, which are subsequently pulled to the poles by the spindle fibers. FTP, identify this step of cell division that follows metaphase.

Chan and Kim at Penn State discovered that crystals can display this phenomenon. One instance of this phenomenon is distinguished by either an A or B phase, and is anisotropic. Some materials that exhibit this phenomenon display a 30 nm Rollin film, and their movement sometimes displays the Onnes Effect.
