Spindle fibers attach to the centromeres at metaphase and separate the splited chromosomes from each other.
Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.

What is the function of the spindle of a floor model drill press?
The spindle moves up and down and carries the shaft of the drill inside it. As the drill turns inside the spindle, the spindle can be lowered, bringing the drill bit into contact with the work.
What is the relationship between centrosomes and spindle fibers?
Spindle Fibers are formed between centrosomes. Centrosomes migrate to opposite ends of the cell during cell division. The spindle fibers function is to anchor the centrosomes and chromosomes into the poles. The chromosomes then reel them selves in using the spindle fiber.
Are spindle fibres and microtubules same?
Yes, spindle fibers and microtubules are essentially the same in that spindle fibers are composed of microtubules. Microtubules are a component of the cytoskeleton, made of tubulin protein subunits, and they play various roles in cellular structure and transport. During cell division, specifically in mitosis and meiosis, microtubules organize into spindle fibers that help separate chromosomes. Thus, while all spindle fibers are microtubules, not all microtubules function as spindle fibers.
What is the function of a spindle bottom bracket in a bicycle's drivetrain system?
The function of a spindle bottom bracket in a bicycle's drivetrain system is to provide support and rotation for the crankset, allowing the pedals to turn smoothly and transfer power from the rider to the bike's chain and ultimately propel the bicycle forward.
What is put together to form the spindle?
The spindle is formed primarily from microtubules, which are protein filaments made up of tubulin dimers. During cell division, specifically mitosis and meiosis, these microtubules organize into a structure known as the spindle apparatus, which helps segregate chromosomes into the daughter cells. Additional proteins, such as motor proteins and spindle assembly factors, also play crucial roles in stabilizing and regulating the spindle's function.
Are spindle fibers and microtubes the same?
Spindle fibers and microtubules are closely related but not identical. Microtubules are the structural components of the cytoskeleton, made of tubulin protein subunits, and play various roles in cell shape, transport, and division. Spindle fibers, specifically, are a type of microtubule that form during cell division (mitosis and meiosis) to help separate chromosomes. While all spindle fibers are microtubules, not all microtubules function as spindle fibers.
What forms spindle fibers?
Spindle fibers are composed of microtubules, which are long, threadlike structures made of a protein called tubulin. These spindle fibers play a key role in cell division by helping to separate chromosomes during mitosis and meiosis.
What is the function of the mitotic spindle during cell division?
The mitotic spindle is a structure made of microtubules that helps separate chromosomes during cell division. It ensures that each new cell receives the correct number of chromosomes.
What is the function of the BB spindle in a bicycle's bottom bracket assembly?
The BB spindle in a bicycle's bottom bracket assembly connects the crank arms and allows them to rotate smoothly, transferring power from the rider's legs to the bike's drivetrain.
Why does the vincristine drug damages the mitotic spindle?
Vincristine disrupts the formation and function of the mitotic spindle by binding to tubulin, a protein that helps in spindle formation. This interferes with the normal process of cell division, leading to mitotic arrest and ultimately cell death.
Where do centrioles function in the cell?
Centrioles function in the cell as part of the centrosome, which is involved in organizing the microtubules during cell division. They help in forming the spindle fibers that separate the chromosomes during mitosis and meiosis.
