1. The Cell Cycle and MitosisCell Cycle

2. Chromosomes o Made of DNA o Each chromosome consists of two sister chromatids attached at a centromere

3. Chromosome

4. Cell Cycle o During the cell cycle, a cell grows, prepares for division, and divides to form 2 daughter cells, each with each of which then begins the cycle again.cell cycle o Order of cell cycle is: Interphase Prophase Metaphase Anaphase Telophase Cytokensis (IPMATC)

6. Interphase Interphase – growth and regular cell activity. o Most of cell life is spent in Interphase. o longest period of the complete cell cycle o DNA replicates

7. Mitosis o Division of somatic cells. o 4 phases. o Remember Interphase is NOT part of Mitosis. Mitosis

8. Prophase o First stage of Mitosis o Chromatin condenses into chromosomes o Centrioles separate and spindle fiber begins to form. o Nuclear membrane breaks down

9. Prophase

10. Metaphase o Second Phase of Mitosis mm o Chromosomes line up in middle of cell. (meet in middle) o Each chromosome connects to spindle fiber at centromere.

11. Metaphase

12. Anaphase o Third Phase of Mitosis o Sister chromatids pull apart or away o individual chromosomes move to opposite ends of the cell.

13. Anaphase

14. Telophase o Fourth and Final Stage of Mitosis o Chromosomes gather at opposite ends of cell, lose distinct shapes o Two new nuclear membranes form.

15. Telophase

16. Cytokinesis o NOT part of Mitosis o Division of cytoplasm after mitosis o Contractile ring tightens creating "cleavage furrow" o Each daughter cell has an identical set of duplicate chromosomes
