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 region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.
What is the structure called that holds two chromatids together?
The structure that holds two chromatids together is called a centromere. It is a region of the chromosome where the two sister chromatids are attached and where the microtubules of the spindle fibers attach during cell division.
What gets pulled apart by spindle microtubules?
Chromosomes in the cell are pulled apart by spindle microtubules during cell division to ensure that each new cell receives the correct number of chromosomes.
What guide or pull chromosomes during mitosis?
The mitotic spindle, comprised of microtubules, guides and pulls chromosomes during mitosis. The spindle fibers attach to the centromeres of sister chromatids and help separate them to opposite poles of the cell during cell division.

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 is the role of kinetochores and microtubules?
Kinetochore allows the attachment of chromosomes to the spindle fiber, which is made ofmicrotubules.Microtubules allowssister chromatidsto separate duringcell division.

Chromosomes in the cell are pulled apart by spindle microtubules during cell division to ensure that each new cell receives the correct number of chromosomes.
What structure holds the sister chromatids to the spindle fibers?
The kinetochore, a protein complex located at the centromere of the sister chromatids, holds them to the spindle fibers during cell division. It serves as a attachment site for microtubules from the spindle apparatus.
What is the function of polar microtubules?
Polar microtubules are a type of microtubule that play a key role in cellular processes such as cell division (mitosis and meiosis). They help in organizing and segregating chromosomes during cell division by attaching to the kinetochore proteins on chromosomes and facilitating their movement. Additionally, polar microtubules contribute to the overall structure and organization of the cell's cytoskeleton.
What guide or pull chromosomes during mitosis?
The mitotic spindle, comprised of microtubules, guides and pulls chromosomes during mitosis. The spindle fibers attach to the centromeres of sister chromatids and help separate them to opposite poles of the cell during cell division.
What microtubules are necessary for sorting the chromosomes in cell division?
The kinetochore microtubules
What does microtublues do?
Microtubules are important for maintaining cell structure within the cell. Microtubules are made of tubulin. They also make up flagella. In animal cells, nine triplets of microtubules make up the two centrioles which are important in cell division. The mitotic spindle is made of microtubules which aid the cell replication process by pulling apart sister chromatids.
What is the role of microtubules during cell division?
Microtubules play a crucial role during cell division by forming the mitotic spindle, which is essential for separating chromosomes. They attach to the kinetochores of chromosomes and help align them at the cell's equatorial plane during metaphase. As the cell progresses to anaphase, microtubules shorten, pulling sister chromatids apart towards opposite poles of the cell. This ensures accurate distribution of genetic material into the daughter cells.
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
