Mitosis consists of five overlapping stages.
In prophase, the chromosomes condense, the nucleolus disassembles, and the spindle forms.
In prometaphase, the nuclear envelope breaks up, and spindle fibers attach to kinetochores.
In metaphase, spindle fibers align replicated chromosomes along the cell's equator.
In anaphase, the chromatids of each replicated chromosome separate, sending a complete set of genetic instructions to each end of the cell.
In telophase, the spindle breaks down, and nuclear envelopes form.
