1. Mitosis and the Cell Cycle Division of the nucleus and the nuclear material (DNA), as well as the cell.

2. The Cell Cycle/ Cell life-span Interphase Mitosis Cytokinesis

3. Interphase G 1 : Growth of cell S: Replication of DNA  (46 chromosomes -> 92 chromosomes) G 2 : Preparation for mitosis  (replicate other organelles)

4. MITOSIS: the nucleus divides Prophase Metaphase Anaphase Telophase

5. Prophase DNA (chromatin) condenses (coils) into chromosomes. Nuclear envelope/nuclear membrane disappears Centrioles move to opposite ends of the cell

8. Metaphase Chromosomes line up on the equatorial plate (middle of the cell) Mitotic spindle forms  Centrioles and microtubules

9. Metaphase Chromosomes line up on the equatorial plate (middle of the cell) Mitotic spindle forms  Centrioles and microtubules

12. Anaphase Chromosomes are pulled apart at the centromere by the microtubules attached to the centrioles in the mitotic spindle.

13. Anaphase Chromosomes are pulled apart at the centromere by the microtubules attached to the centrioles in the mitotic spindle.

16. Telophase Chromosomes are at opposite ends of the cell Two nuclear envelopes reform around each 46 set of chromosomes Chromosomes uncoil and the DNA is now called chromatin

19. Cytokinesis Division of the cytoplasm. TWO new IDENTICAL cells are formed.
