1. The Cell Cycle
This is the growth and division of cells that create new cells.
It consists of
Interphase
Mitosis
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

3. What is all that G1/S/G2/M/C stuff?
G1 Phase (Gap 1)
This part of the cell cycle is where the cell spends most of its functional life doing cell stuff (whatever job that cell happens to have).
A cell division event eventually begins. Lots of stuff can make that happen:
- Maybe dead or dying cells need to be replaced.
- Maybe the cell needs to grow larger.
- Unicellular critters need to reproduce.
Remember that the SA/V ratio can’t get too big or stuff can’t get in and out of a cell fast enough.

4. S (Synthesis) This is when DNA replication takes place.
DNA goes from a single stranded molecule to a pair of identical strands.
It is NOT formed into chromosomes yet! It’s still chromatin!

5. G2 Phase (Gap 2) The final part of Interphase.
The cell is almost ready to begin dividing.
Protein synthesis is happening…a lot (remember…proteins are enzymes or structural)! The spindle fibers are made of proteins so…gonna need that soon (in mitosis).

6. Mitosis *Notice that it doesn’t take up that much of the cell cycle!

7. Cytokinesis
This is very last stage and is when the daughter cells actually separate…the middle pinches in and keeps tightening until the cell divided
there are now two new fully-functioning cells identical to the parent cell.
In plant cells, a cell plate forms. The new cell wall will form from this structure.

8. Let’s Look at this in a different way…M’kay.
