Mitotic events are separated from each other by interphase, during which a cell is not in the process of dividing. Mitosis is comprised of five main phases: prophase, prometaphase, metaphase, anaphase and telophase. Mitosis is important for cell replacement for the development of embryos after sexual reproduction, and the growth of organisms after this stage and for asexual reproduction. This is to ensure that the chromosomal number is conserved throughout cell replication if this did not occur, a diploid cell would divide to produce a haploid cell, which would later divide to contain only half the number of chromosomes in the haploid, and so forth. Before mitosis, the number of chromosomes in the cell is doubled via chromosome replication, transforming the cell from a diploid (2n) cell to a tetraploid (4n) cell.

This is followed by the reformation of the nuclear envelope, uncoiling of the DNA, and disappearance of the spindle fibers. During the last phase of mitosis, telophase, the two sets of chromosomes reach the opposite poles of the cell. Next, during anaphase, the centromeres holding the sister chromatids together are divided and the sister chromatids are pulled apart by the spindle fibers to opposite poles of the diving cell. The spindle fibers are completely formed and are attached to each sister chromatid of the chromosomes. In the next phase, metaphase, the chromosomes line up along the metaphasic plate. In prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers. Mitosis has four sequential stages: prophase, metaphase, anaphase, and telophase. This allows for the separation of each sister chromatid into its respective daughter cell. The division of the centromeres occurs during anaphase. Centromeres are the structures at the center of each chromosome that hold the sister chomatids together.
