The are made up of microtubules, associated proteins, asters, centrosomes, etc. So mitotic spindles are made up of more than just microtubules.

When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the duplicated chromosomes. The attachment of microtubules to chromosomes is mediated by kinetochores, protein complexes on the chromosome. Spindle microtubules can be divided into three major classes: kinetochore microtubules, which form Overview of the Mitotic Spindle.

Mitotic spindle vs spindle fibers

Kinetochore fibers are the main generators of forces that move the chromosomes during mitosis. When sister kinetochores become attached to microtubule fibers extending from the opposite spindle poles, which is known as biorientation, these fibers hold the chromosomes near the spindle equator (Maiato et al.

Spindles somes are usually associated with spindle fibers, r This orientation is dependent on the distribution of actin retraction fibers, as well as on astral microtubules 65666768. It should be noted that knockdown of LGN or  Tubulin protein and RNA · Spindle fibers are the cellular structures which are mainly used during cell division.

It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell. Besides chromosomes, the spindle apparatus is composed of hundreds of pr Spindle fibers are highly active during mitosis.
