1. Mitosis

2. Mitosis is divided into four phases:
Prophase
Metaphase
Anaphase
Telophase

3. Prophase Longest phase of mitosis. Chromosomes condense.
Centrioles separate.
Spindle begins to form.
Nuclear envelope breaks down.

4. Metaphase Chromosomes line up across the center of the cell.
Each chromosome is connected to a spindle fiber at its centromere.

5. Anaphase
The sister chromatids separate into individual chromosomes and move apart.

6. Telophase
Chromosomes gather at opposite ends of the cell and lose their shape.
Two nuclear envelopes form.

7. Cytokinesis The cytoplasm pinches in half.
Each daughter cell has an identical set of duplicate chromosomes.

8. Mitosis
