FC: Erin Maree Gubatanga | Mitosis
1: Mitosis is the duplication and division of the nucleus of a cell and its chromosomes during cell reproduction.
2: Interphase | Interphase proceeds in three stages, G1, S, and G2 and is the longest phase. | G1 phase is when the cell increases in size in preparation for cell division. This is the first gap phase. | S phase is the second part in interphase. It is the part when the cell copies its DNA. S stands for synthesis. | G2 phase is the final stage of interphase. Organelles are copied.
5: Prophase | an | Prophase is the longest phase. It is when the Nuclear membrane disintegrates. The nucleolus then goes away. Chromosomes appear as chromatids, then mitotic spindle forms. The centrosomes move to opposite poles.
7: Metaphase is the shortest phase in the cycle. is when the chromosomes line up at the middle of the cell. The centromeres connect to the spindle fibers. | Metaphase
8: Anaphase | this is the part when the chromosomes separate to opposite poles
10: A Picture is Worth 1,000 Words | Telophase and Cytokinesis | Telophase is when the nuclei come back together. The nucleolus also reappears. The chromosomes begin to uncoil. Cytokineses is the final stage of mitosis when they finally become two in dependent cells, the cytoplasm parts.
