The spindle is the structure that pulls the chromatids to opposite ends of the cell during the cell division processes of mitosis and meiosis.
Witryna6 lis 2024 · Mitotic spindle is mainly made of microtubules. These microtubules are made by polymerisation of globular tubulin proteins. What are the mitotic spindles made of? microtubule The mitotic spindle is the microtubule-based bipolar structure that segregates the chromosomes in mitosis. The poles of the mitotic spindle are made … WitrynaThe mitotic spindle begins to form. The spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis. In prophase, the spindle grows between the centrosomes as they move apart. How is mitotic spindle formed?
Witryna30 gru 2024 · The mitotic spindle. The spindle is made of microtubules that originate from the centrosomes, which have migrated to opposite sides of the cell. There are three types of spindle microtubules: the kinetochore microtubules (K), polar microtubules (P), and astral microtubules (A).
