One thing I learned in this 3-class lesson is about how the process of mitosis and meiosis. In the process of mitosis, there are six steps which are
interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. Interphase is when DNA is replicated. Prophase is when the membrane dissolves and spindle fibers move to opposite poles. Metaphase is when the spindle fibers attach to centromeres and chromosomes pulling them to the opposite ends. Anaphase is when spindle fibers shorten. Telophase is when chromosomes reach the opposite ends and the spindle fibers disintegrate. Cytokinesis is when daughter cells splits apart and the two daughter cells have the same numbers of chromosomes. In meiosis the steps are exactly the same as mitosis from the steps interphase to prophase.
