Web5 de mai. de 2000 · Microtubules in ts-arp1 cells had opportunity to interact with the bud cortex. Microtubules were oriented properly (Fig. 8) and always penetrated into the bud (128/128 cells). Furthermore, microtubules frequently made sweeping end-on interactions with the bud cortex (Fig. 7 A). WebIn mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules. Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.

The walls of the microtubule are made of polymerized dimers of α-tubulin and β-tubulin, two globular proteins (Figure \(\PageIndex{4}\)). With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton.
