1. Definition for the Cell Cycle: The process in which a cell grows and divides. Some cells take 24 hours to go through the cell cycle (animal cells) and some do not divide at all (neurons).

2. How it happens and what follows.
Interphase: G1, S, G2.
1. G1: grows in size and manufactures more
2. S (Synthesis): where the cell replicates the cell's DNA, only one copy is made.
3. G2: the cell continues to grow and produces a number of molecules
4. M: the cell's DNA condenses into chromosomes and are then are sorted into an even amount.
They are then split into two different cells.
- a) Interphase: The very end of the Cell Cycle, where the cell becomes two separate cells.
- b) Prophase: The Beginning of Mitosis: the centrosomes move towards the opposite poles of the cell. The sister chomotids become more visible as they condense.
- c) Metaphase: The chromatids are lined up between.
- d) Anaphase: The chromotids begin to separate and become chromosomes and move towards the ends of the poles.
- e) Telophase: The chromosomes arrive at the poles, finally, and begin to grow their own nuclear membranes.
- f) Cytokinesis: A furrow is created in the parent cell and eventually "pinches" the two new cells apart.
And this is how cells reproduce!
