Modeling Mitosis

Interphase:

The interphase is the longest segment of the cell cycle. In this stage, the cell grows and copies its DNA before moving into the mitosis cycle.

 

Prophase:

In this phase, the duplicated chromosomes will curl into an X-shape chromosome. Then the nucleolus will disappear and  the nuclear membrane will begin to disintegrate. While the tiny shaped tubes called spindle fibres will begin to form.

Late prophase:

Then, when the spindle fibres is completely formed. The chromosomes will attach to the spindle fibres at their centromeres, while the nuclear membrane disappears.

 

Metaphase:

The spindle fibres will pull the X-shaped chromosomes into a single row across the midsection of the cell.

 

Anaphase:

The anaphase is when the spindle fibres contracts and shortens. This will pull the centromere apart, granting permission for the sister chromatids to move to the opposite pole of the cell.

 

Telophase:

This is the final stage of Mitosis, the chromosomes will now be at each pole of the cell. While, the spindle fibres will start disappearing and the nuclear membrane forms around the chromosomes. A nucleolus appears in each nucleus. Now two nuclei are in one cell making the cell ready to divide itself.

Cytokinesis:

Cytokinesis is the final process of mitosis, in this stage the cell divided itself into two.

One thought on “Modeling Mitosis

  1. Good work illustrating what happens during mitosis. Your anaphase picture is really late prophase (the chromosomes are not pulled apart in the picture), however. Also your telophase is anaphase, and your cytokinesis is telophase.
