Medical Video: The Stages of Mitosis

Summary

This video is called, "Medical Videos The Stages of Mitosis", an animated rendition of mitosis. At the beginning of the video, various organelles including the Golgi apparatus and mitochondria are shown. Later, at about 0:19, the video shows the cell's nucleus going about its usual metabolic processes during interphase, with the DNA still as loose chromatin strands. At 0:28 during prophase, you are able to see the DNA solidifying into chromatin. The nuclear envelope breaks down, showing the cell is preparing to divide. At 0:36 during metaphase, you see the chromosomes lining up along the middle of the cell with the spindle microtubules attached to the centromeres. Anaphase is demonstrated during 0:50 when the sister chromatids separate from each other. The two new nuclear envelopes immediately reform in telophase at 0:57. The organelles, the nuclei, and the cytoplasm divide into two different cells at 1:06 as cytokinesis. You can tell from the video that the cells in the demonstration are animal cells. A cell plate forms between two dividing plant cells and the two daughter cells in the video split apart.

Relevance to Class

In class, we are studying the cell cycle and in particular, mitosis. This video shows the stages of mitosis though animation. Because of what was learned in class, the viewer of this video can immediately identify the cells as animal cells instead of plant cells. A viewer who has actually paid attention in class can also identify the stages of mitosis and the various organelles shown. (Forgetting the fact that the stages are labeled in the corner of the video). In order to understand anything that happens in the video, you need to have an understanding of what happens in class.
