Why do cells produce daughtercells identical to themselves when undergoing mitosis?
During mitosis, the duplicated chromosomes, abridge and join to fibers that takes out one copy of each chromosome to opposite sides of the cell, resulting two genetically alike daughter nuclei. Then, the cell may undergo cytokinesis process, producing two alike daughter cells. Cytokinesis occurs during mitosis and it represents the cytoplasm division process. Cytokinesis begins in one of the main stages of mitosis, called anaphase, and it reaches completion in the stage called telophase.
There exists the possibility that mistakes to occur in mitosis. One of them is known as nondisjunction and it represents the failure of the separation of homologous chromosomes or chromatides. Other mistake, known as tripolar or multipolar mitosis, is represented by the creation of more than two daughter cells. Other mitotic errors can lead to mutations or apoptosis.
