Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing.

1. Compare mitosis and meiosis, and their role the cell cycle; Objectives:

2. Have you ever looked down to see a wound in your arm and you have no idea how you got it? Then a few days later, it’s gone. Have you also looked at your old photographs and realize that you were taller/older than five years ago? What’s common with these things? Check this out!

3. Mitosis is one big thing that they have in common Mitosis is a type of cell division performed by the cells of your body. Cells need to divide. If they did not divide you will not grow. Is one reason you were taller than five years ago.

4. Let’s look at another type of cell division! that leads to genetic diversity.

5. You and your sister have the same parents but still, you look different from each other.

6. Cell Cycle 3 Stages of Interphase G1 (1 st Gap) Synthesis G2 (2 nd Gap)

7. Where the cell prepares to divide. – Cell grows. – DNA is replicated. – Mitotic cell division produces daughter cells identical to the parent. – Repeat. The timing of replication and cell division is highly regulated.

8. Where all the DNA is copied by the cell. S stands for the synthesis of DNA.

9. G2 phase where it organizes and condenses the genetic material, or begins to condense the genetic material, and prepares to divide after the DNA is copied and there is a full extra collection of all the genetic material.

10. Cytokinesis the cytoplasm divides and the parent cell becomes two daughter cells.
