During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.

What else can I help you with?
What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.
In mitosis what pulls the sister chromatids apart?
During mitosis, the mitotic spindle, which is made of microtubules, pulls the sister chromatids apart. The microtubules attach to the kinetochores located on the centromere of each sister chromatid and exert force to move them towards opposite poles of the cell.
What is the role of spindle fibers in mitosis?
They pull the sister chromatids apart.
During what phase do the centromeres of sister chromatids disjoin and the chromatids separate?
During the anaphase stage of mitosis, the centromeres of sister chromatids disjoin and the chromatids are pulled apart to opposite ends of the cell by the spindle fibers.
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
What is role of spindle fibers in mitosis?
They pull the sister chromatids apart.
What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.
Are spindle fibers used in mitosis?
Yes. They are used to separate the sister chromatids apart.
In mitosis what pulls the sister chromatids apart?
During mitosis, the mitotic spindle, which is made of microtubules, pulls the sister chromatids apart. The microtubules attach to the kinetochores located on the centromere of each sister chromatid and exert force to move them towards opposite poles of the cell.
What is the role of spindle fibers in mitosis?
They pull the sister chromatids apart.
What structure are spindles attached to that help pull the paired chromosomes apart?
Spindle fibers attach to the centromeres on the sister chromatids.
During what phase do the centromeres of sister chromatids disjoin and the chromatids separate?
During the anaphase stage of mitosis, the centromeres of sister chromatids disjoin and the chromatids are pulled apart to opposite ends of the cell by the spindle fibers.
The separation of the sister chromatids marks the beginning of what structure?
The separation of sister chromatids marks the beginning of anaphase in mitosis or meiosis. During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
What stage of mitosis is when sister chromatids separate into individual chromosomes?
Anaphase is the stage of mitosis when sister chromatids separate into individual chromosomes. During this stage, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
During cell division this shortens to pull the chromatids apart.?
spindle fibers
How are chromatids separated?
Chromatids are separated during cell division by a structure called the mitotic spindle, which attaches to the centromere of each sister chromatid. The spindle fibers then pull the sister chromatids apart towards opposite poles of the cell, ensuring that each daughter cell receives the correct number of chromosomes.
