This is a PowerPoint animation of an animal cell dividing during mitosis.

1. Nucleus  with a nuclear envelope and Chromatin inside Do you remember what chromatin is? chro·ma·tin (krō’-ma-ten) n. A complex of nucleic acids and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division. A cell with four chromosomes

2. During Prophase, the nuclear envelope breaks down and a spindle forms between two centrioles. Example:

3. Metaphase  Chromosomes are now doubled and are aligned at middle of cell, chromosome are attached to centrioles by spindle fibers.

4. Metaphase  Chromosomes are now doubled and are aligned at middle of cell, chromosome are attached to centrioles by spindle fibers.

5. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.

6. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.

7. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.

8. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.

9. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.

10. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.
