Microtubule Falls Apart (video) University of California - Berkeley Loading video... Caption This video shows how the microtubule rapidly peels apart once the growing tubulin cap disappears. This peeling or depolymerization does work inside the cell. A chromosome attached by its kinetochore to a microtubule will be pulled because the kinetochore remains attached to the shortening microtubule as it peels apart.
