How long does it take for a cell to go through mitosis?

Mitosis is the process by which a cell duplicates its chromosomes, in order to generate two, identical cells. It is generally followed immediately by cytokinesis which divides the cytoplasm and cell membrane. This results in two identical cells with a roughly equal distribution of organelles and other cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle, the division of the mother cell into two daughter cells, each with the genetic equivalent of the parent cell. Mitosis occurs exclusively in eukaryotic cells. In multicellular organisms, the somatic cells undergo mitosis, while germ cells — cells destined to become sperm in males or ova in females — divide by a related process called meiosis. Prokaryotic cells, which lack a nucleus, divide by a process called binary fission.
