M phase is the most dramatic period of the cell cycle, involving a major reorganization of virtually all cell components. During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis). Although many of these events have been discussed in previous chapters with respect to the structure and function of the nucleus and cytoskeleton, they are reviewed here in the context of a coordinated view of M phase and the action of MPF.

The centromere of each doubled chromosome becomes attached by thread-like spindle fibers to the centrioles which are at polar opposite sides of the cell.
Before mitosis begins, cells are in the interphase stage, which is the rest period between mitotic divisions. At this time, the chromosomes are not identifiable but are an undifferentiated loose mass of stretched out DNA molecules within the nucleus. Chromosome replication and other cell processes are occurring in preparation for mitosis. In addition, cells carry out normal metabolic activities at this time. Most mammal somatic cells, including those of humans, spend at least 90% of their time in interphase.
