Modelling Mitosis

Interphase:

Description of the photo: This phase is the longest cell cycle stage. It has chromatin in the nucleus and carries out normal functions. The cell membrane, the nucleus and nucleolus are intact.

Late stage of Interphase:

Description of photo: This is the stage where The DNA is copied during the interphase. This image demonstrates the replicated DNA molecules joining together to form sister chromatids.

Early Prophase:

Description of the photo: This is the stage where spindle fibres begin forming and the nucleolus begins to disappear to allow the nucleus to start dividing. This is preparing for the division of chromosomes.

Late Prophase:

Description of photo: This is the stage where spindle fibres begin to attach to centromeres of chromosomes in preparation of organizing them. Chromosomes also become more condensed at this stage, and the nucleolus completely disappears.

Metaphase:

Description of photo: This is the stage where the chromatids attach to the spindle fibres at the centromere and line up in the center of the cell to be ready to divide the cell. One half of the cell and the other half has 46 chromosomes.

Anaphase:

Description of the photo: This is the stage where the spindle fibres are pulling apart the sister chromatids. The end of this phase, this stage is where we have 46 daughter chromosomes on each side of the cell.

Telophase:

Description of photo: The is the stage where the cell pinches off in the center, forming two daughter cells.

Cytokenesis:

Description of the photo: This is the stage where the Nuclear membrane and nucleolus reappear in each new cell and the chromosomes fades into chromatin.

  1. Great work including pictures, captions, and descriptions of the complete process of mitosis. Your post is very effective in explaining how mitosis works. Great work using some of the provided pictures in combination with your own.
