WebFIBERS of the spindle (green) in two mitotic kangaroo cells have been made visible by staining, as have the chromosomes (orange-red) attached to each spindle. One cell is in the stage of mitosis called metaphase (top): its chromosomes, which were initially scattered throughout the nucleus, are aligned at the spindle equator. WebMitosis conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei. Prophase The first stage of mitosis, in which the chromatin condenses into discrete chromosomes visible with a light microscope, the mitotic spindle begins to form, and the nucleolus disappears but the nucleus remains intact. sleep restoration pillows
