Lab report for Mitosis Use the link for vocabulary and write down the definitions of each of the following terms: In your own words, summarize what is occurring in each phase of mitosis (don't just copy): Interphase: This is the phase where the cell prepares for division by growing and replicating its DNA. It is a period of intense activity and growth. Prophase: During prophase, the chromatin condenses into chromosomes, the nuclear membrane breaks down, and the spindle fibers begin to form. The chromosomes become visible under a microscope. Metaphase: In metaphase, the chromosomes line up along the equator of the cell. The spindle fibers attach to the centromeres of the chromosomes, ensuring that they are properly aligned. Anaphase: Anaphase is the phase where the sister chromatids separate and move towards opposite poles of the cell. The spindle fibers shorten, pulling the chromatids apart. Telophase: Telophase is the phase where the chromosomes reach the opposite poles of the cell. The nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense. Cytokinesis: Cytokinesis is the final stage of mitosis, where the cell physically divides into two daughter cells. The cytoplasm and organelles are evenly distributed between the two cells, and each daughter cell enters interphase to begin the next cell cycle.
