Mitosis. Representation of various steps of mitosis : -During prophase, the chromatin of the nucleus of the mother-cell organizes into 46 pairs of chromosomes, the nuclear envelope breaks, the centrioles move to the opposite poles and the mitotic spindle forms itself. The metaphase is the stage during which the chromosomes align at the centre of the mitotic spindle . - The anaphase is the phase during which the elements of the cell starts to organize and separate in an identical manner so as to give two daughters cells. The telophase is the stage during which the two cells start to separate and the nucleus reforms. At interphase, the chromatin of the nucleus of the two identical daughters cells have decondensed.
