1. The Cell Cycle
Foldable

2. Pick up all 3 handouts
Put Cell Cycle and DNA Vocab. sheets on page 5 and 6 in your notebook
Take out your computer and watch the Mitosis EDpuzzle
You will have 15 minutes before this becomes homework

3. The Cell Cycle Foldable
Today we will go over the cell cycle by creating a foldable
Take your handout and fold it in half so that it looks like this
The Cell Cycle
Mitosis
cytokinesis
Interphase

4. The cell cycle The life of a cell
The alteration between dividing and not dividing

7. Interphase The nondividing part of the cell cycle
The nuclear membrane is intact throughout interphase
Split into 3 phases
G1 phase, S phase, and G2 phase

8. G1 Phase Growth phase The longest phase of the cell cycle
The DNA is loosely spread out

9. S Phase Synthesis phase DNA is replicated
2 sister chromatids are formed, attached at the centromere

10. G2 Phase 2nd Growth Phase Cell prepares for division
Makes the spindle fibers it needs to move chromosomes around

11. Mitosis
Division of genetic material and nucleus of the cell leading up to cell division

12. Prophase DNA appears as chromatin coils that pair up as they condense
Nuclear membrane disappears

13. Metaphase Chromatid pairs line up along the middle of the cell
Centrioles form spindle fibers attaching the chromatid pairs at their centromeres

14. Anaphase
Chromatid pairs separate and are pulled towards the cells poles by the spindle fibers

15. Telophase
Cells get ready to divide into two by forming new nuclear membranes around the separated sets of chromosomes

16. Cytokinesis After mitosis ends
Cytoplasm and organelles of the cell divide forming two identical cells
