What joins arms together and is the place where spindle fibers attach to each chromosome?
The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
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 a disk protein at the centromere region of the chromatid that serves as a platform for assembling microtubules?
When a chromosome has replicated and is preparing for division, the two chromatids are connected by the centromere. The centromere is the site where the kinetochore forms. The kinetochore forms the attachment with the spindle fibers.
Where is the region where the identical DNA molecules are most tightly attached to each other?
Identical DNA molecules are most tightly attached to each other at the region known as the centromere, which is located in the middle of the chromosome. The centromere plays a crucial role in cell division by providing the attachment site for spindle fibers during mitosis and meiosis.
What is the difference between kinetochore and centromere?
The centromere is a region of a chromosome that plays a role in chromosome segregation during cell division. The kinetochore is a protein structure located at the centromere that helps attach the chromosome to the mitotic spindle during cell division. In summary, the centromere is a DNA region while the kinetochore is a protein structure located within the centromere region.
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 joins arms together and is the place where spindle fibers attach to each chromosome?
The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
What structure do copied sister chromatids remain attached?
Copied sister chromatids remain attached at the centromere region, which is a specific DNA sequence on the chromosome. The centromere serves as the attachment site for the spindle fibers during cell division, ensuring that each daughter cell receives one copy of the chromatid.
What is cetromere?
The centromere is a region of a chromosome that plays a critical role in cell division. It is responsible for ensuring proper segregation of chromosomes during mitosis and meiosis. The centromere serves as the attachment site for spindle fibers that help pull apart sister chromatids.
To which part of the centromere do mitotic spindle fibers attach during prometaphase?
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.
What is the region of a chromosome where two sister chromatids attach?
The region of a chromosome where two sister chromatids attach is called the centromere. It appears as a constricted area on the chromosome, serving as a site for protein binding and attachment of spindle fibers during cell division. The centromere plays a crucial role in ensuring proper segregation of chromosomes during mitosis and meiosis.
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 a disk protein at the centromere region of the chromatid that serves as a platform for assembling microtubules?
When a chromosome has replicated and is preparing for division, the two chromatids are connected by the centromere. The centromere is the site where the kinetochore forms. The kinetochore forms the attachment with the spindle fibers.
Where do spindle fibers attach to chromosomes?
I am at least 70% sure that they attach to the centriole which binds the chromosome together.Centrioles do not have much to do with chromosomes. Centrioles are found just floating in the cytoplasm, while chromosomes are in the nucleus. Chromatins, strands the chromosomes are make up of, are connected by the centromere. Therefore the spindle fibers probably attach to chromosomes in the nucleus, though I, as well, am not entirely sure.
Where is the region where the identical DNA molecules are most tightly attached to each other?
Identical DNA molecules are most tightly attached to each other at the region known as the centromere, which is located in the middle of the chromosome. The centromere plays a crucial role in cell division by providing the attachment site for spindle fibers during mitosis and meiosis.
What is a kinetechore?
a region within the centromere that serves as a point of attachment site for the mitotic spindle (spiindle apparatus)
What is the difference between kinetochore and centromere?
The centromere is a region of a chromosome that plays a role in chromosome segregation during cell division. The kinetochore is a protein structure located at the centromere that helps attach the chromosome to the mitotic spindle during cell division. In summary, the centromere is a DNA region while the kinetochore is a protein structure located within the centromere region.
