WebVideo transcript. - Let's talk about microtubules in more detail. So, first we'll discuss the structure. So, microtubules are made up of two proteins. The first is called alphatubulin, and the second similar protein is called betatubulin, and the alphatubulin and betatubulin will join together to form a dimer. A dimer's simply when you have two ... WebSpindle fibers are protein structures that form early in mitosis, or cell division. They consist of microtubules that originate from the centrioles, two wheel-shaped bodies located in the centromere area of the cell. The centromere is also known as …
