2. Mitosis Drawing Draw, color, and label: –The life cycle of a cell including Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. –Make sure to label Nucleus, Nuclear Membrane, DNA/Chromosomes, Parent Cells, Daughter Cells. –Show what is happening to the DNA/Chromosomes at each step of the process.

3. A Cell Life Cycle

4. A Cell’s life… Consists of 3 main parts 1. Interphase (I) – cell is hanging out. 2. Mitosis – If a cell decides to divide it undergoes Mitosis (PMAT) 3. Cytokinesis (C) – Two daughter cells created

5. Interphase Phase 1- Interphase –Cell resting –DNA is in little single threads. –DNA is doubled and the cell gets bigger.

6. Mitosis Phase 2- Prophase –Mitosis begins –Chromosomes are in their “x” like shape. –Centrioles move to poles –Spindle fibers connect centrioles

7. DNA change from phase 1 to 2 Interphase DNA is Chromatin (bunch of squiggles with no clear shape ) Prophase DNA is organized into sister chromatids which make a chromosome.

8. Centriole Change from interphase to Prophase Interphase Prophase – Centrioles start to move to poles and spindle fibers start to connect them. Nucleus

9. Mitosis Phase 3- Metaphase –They line up in middle of cell –Chromosomes attach to spindle fibers

10. Mitosis Phase 4- Anaphase –Sister chromatids pull apart –One sister of each pair goes to opposite ends of the cell

11. Mitosis Phase 5- Telophase –2 new nuclei form –Mitosis is complete –Chromosomes are undone again (chromatin)

12. Mitosis Phase 6- Cytokinesis –Cytoplasm pinches in to form 2 new identical daughter cells

13. Which phase of mitosis is this? Explain…..
