Cell Cycle
Cell division is the process by which a cell replicates itself to produce two daughter cells. It involves a long interphase period where the cell grows and its DNA is copied, followed by mitosis where the nucleus and its chromosomes are divided into two identical copies through the stages of prophase, metaphase, anaphase and telophase. Cytokinesis then partitions the cytoplasm and organelles to complete the formation of the two new daughter cells.

- 1. Cell Cycle andCell Division
- 2. Cell Division -the process a cell undergoes in order to make copies of itself. Why do cells divide?
- 3. DNA & ChromosomesDNA is chromatin strands and chromosomes
- 4. Interphase (about90% of the cell cycle time) Cell mature Chromosomes copy themselves
- 5. Mitosis: Prophase Nuclearmembrane disappears Spindle fibers form at the poles of the cell
- 6. Mitosis: Metaphase Chromosomesline up at the middle 2 Spindle fibers attach to each centromere
- 7. Mitosis: Anaphase Centromeressplit and the fiber strands pull the chromosomes to each pole
- 8. Mitosis: Telophase 2new nuclei form at two poles of the cell where chromosomes have gathered Mitosis (division of one nucleus into two identical nuclei) is complete
- 9. Cytokinesis Two newdaughter cells are formed
