    Please help me.
    Why do you suppose cytokinesis generally occurs in the cell's midplane?
    What would happen if a cell underwent mitosis but not cytokinesis?
    Thanks

    i gather its to ensure that the chromosomes do seperate complettly from each other. the spindl fibers seperate and drag the chromosomes to oppisite poles of the cell, and cytokinesis occurs in the middle so its right between both poles, away from the chromosomes.

    im not quite sure what would happen if cytokinesis did nto occur. i'd say that the cell would simply die away, or not function.

    it could continue with doubles of all the information, im not sure.

    Feel free to correct any false information, which unknown to me, may be included in my posts. (also - let this be a disclaimer)

    I'm pretty sure the only problem there might be with having doubles would be more possibility for mRNA to be created, and with all the negative feedback loops the cell has I think that would be taken care of pretty quickly.

    But what the books states that some cell can have 2 and more nuclei.

    mmm yes. Muscle cells. I believe this is because the cell is soo large. Some single cell organisms have multiple nulei I think too. Forgot what they are called.

    there are instances of cell not undergoing cytokinesis as in Salivary glands of dorsophila, but when human cell is concerned i belive the cell would not b stable which is observed when the cell is treated with mitotic poisons
