1. Mitosis
A Sequencing Activity

2. Prometaphase The nuclear membrane dissolves
Proteins attach to the centromeres creating the kinetochores.
Microtubules attach at the kinetochores and the chromosomes begin moving.

3. Interphase
Interphase is the "holding" stage or the stage between two successive cell divisions. DNA replicates, the centrioles divide, and proteins are actively produced.

4. Prophase
Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes.
The nucleolus disappears.
Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres.

5. Anaphase
Attachments between the two sister chromatids of each chromosome break and are now separate chromosomes that move to opposite spindle poles.

6. Telophase Lastly, the chromosomes decondense.
New patches of membrane fuse to form new nuclear envelopes around them.

7. Metaphase
The microtubules penetrate the nuclear region and form a spindle apparatus. They attach to sister chromatids of each chromosome.
All the chromosomes line up at the equator of the spindle.
