![]() ![]() Spindle fibers begin to form a bridge between the ends of the cell. Pairs of centrioles move to opposite sides of the nucleus. Telophase: Reversal of prophase and prometaphase eventsĭuring prophase, chromosomes in the nucleus condense. The gametes are produced by a different division method called meiosis. The sperm and ova are gametes or sex cells. Mitosis happens in all types of dividing cells in the human body except with sperm and ova. Since the two chromatids are identical to each other, they are called sister chromatids. The chromosomes are now two chromatids joined at the centromere. At the beginning of mitosis the chromosomes wind up into visible objects that can be seen with a light microscope. The genetic information is in the DNA of the chromosomes. ![]() The chromosomes of a cell are copied to make two identical sets of chromosomes, and the cell nucleus divides into two identical nuclei.īefore mitosis, the cell creates an identical set of its own genetic information – this is called DNA replication.
