3. MitosisMitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes are replicated.Chromosomes are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.The length of the Cell Cycle depends on the type of cell. Human liver cell takes 22 hours. Human brain cell never leave Interphase.

5. The Cell CycleThe regular series of growth and cell division Stage 1 Interphase Stage 2 Mitosis Stage 3 Cytokinesis

6. Cell Cycle

7. Cell Cycle Interphase Cell grows to mature size Cell makes a copy of DNA Cell prepares to divide into 2 cells Mitosis Prophase Metaphase Anaphase Telophase Cytokinesis Cell membrane pinches inward Each daughter cell winds up with identical chrosomomes Organelles and cytoplasm are sent to each daughter cell

8. Cell Division by Mitosis

9. Mitosis Prophase Chromatin condense Spindle fibers form bridge Nuclear membrane breaks down Metaphase Chromosomes line in middle Chromosomes attach at spindle fiber Centromeres hold chromosomes together Anaphase Centromere splits Chromatids move to opposite sides Cell becomes stretched at either end Telophase New nuclear membrane forms around each region of chromosome
