Answer:
Mitosis is composed of 5 steps:
1)prophase
2) metaphase
3) anaphase
4) telophase
5) cytokinesis
Beginning from prophase, the nuclear envelope and nucleolus begin to dissolve and the spindle fibers start to form. In metaphase, the chromosomes form a line down the middle of the chromosome and the fully formed spindle fibers attach to the kinetochore, which are in turn attached to the centromere which is holding the sister chromatids ,which make up the chromosome, together. During anaphase, the sister chromatids are pulled apart and the centromere ruptures. Each chromatid is pulled to a pole on the opposite side of the cell. Telophase is simply prophase in reverse. The nucleolus is reformed, one around each chromatid, as well as the nuclear envelope and the spindle fibers begin to dissolve. Lastly, cytokinesis is the physical separation of the cell into two daughter cells,
