After the G2 phase, the cell goes thru another growth period. The cell will gather energy in order to prep for whats coming: Mitosis. The first phase of mitosis is Prophase. During Prophase, the chromatin fibers condense and shorten to chromosomes that can now be seen with aid from a light microscope. Microtubules also appear and prepare to hold sister chromatic im correct alignment for separation. Metaphase is the second phase. Microtubules align sister chromatids at the exact center of the mitotic spindle aka metaphase plate. The following step is Anaphase. The centromeres split, separating the 2 identical sister chromatids. Once the chromatids are separated, they are called chromosomes. Telophase comes after anaphase. It is the final stage of mitosis. The identical sets of chromosomes are now at opposite sides of the cell. The nuclear envelope now re-forms around each mass of chromosomes, nuclei reappear within each nucleus. After these phases, Cytokenisis occurs. This is the division of the cell's cytoplasm and organelles into 2 cells. A cleavage furrow is formed during Anaphase.
