The changes now taking place are the reverse of those that occurred during prophase: the chromosomes uncoil, new membranes form around the nuclei, and the fibers of the spindle disappear. Cytokinesis is the final physical cell division that follows telophase, and is. In the last phase-telophase-the cell divides. These phases are prophase, prometaphase, metaphase, anaphase, and telophase. In this way a complete set of chromosomes migrates toward each centriole. Once the chromatids separate, they are called chromosomes. As the third phase-anaphase-begins, the chromatids separate and move to opposite ends of the cell. The second phase of mitosis is metaphase, in which the chromosomes move into the equatorial plane of the spindle. Many of these from one centriole join with strands from the other to form the spindle. From the centrioles, long, thin strands extend in all directions. The long, threadlike material of the nucleus coils up into visible chromosomes, and the nuclear membrane disappears. In the first phase-prophase-a centriole, located outside the nucleus, divides. The process of mitosis is continuous, but it is possible to identify four general phases, each characterized by specific activity.
