Modeling Mitosis

Stage 1 – Interphase

The chromosomes begin to duplicate and become two identical chromatins joined at the centromere.

 

Stage 2 – Mitosis – Early Prophase

In the nucleus the chromosomes condense and in the cytoplasm, spindle fibers form.

Stage 2 – Mitosis – Late Prophase

The nuclear membrane breaks apart and the spindle fibers start to attach to the chromosomes.

Stage 2 – Mitosis – Metaphase

After the spindle fibers attach to the chromosomes and the chromosomes line up in the middle of the cell.

Stage 2 – Mitosis – Anaphase

the spindle fibers shorten and the centromere divides so that each chromosome becomes two separate chromatins.

Stage 2 – Mitosis – Telophase

The nuclear membrane forms around each set of chromosomes, chromosomes spread back out into new nucleus and the spindle fibers break down.

Stage 3 – Cytokinesis

The cell membrane separates into two separate cells that are exactly the same.

  1. Great work including pictures, captions, and descriptions of the complete process of mitosis. Awesome job including early and late prophase. Your post is very effective in explaining how mitosis works.
