Microtubules
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Microtubules are the cytoskeleton's widest, hollow fibers, built from tubulin dimers, that resist compression and track vesicle movement and chromosome separation.
Show
Microtubules pull replicated chromosomes to opposite ends of a dividing cell and form the structural core of centrioles.
Watch for
Microtubules resist compression the way microfilaments resist tension — different stresses, different fibers.
