What else can I help you with?
Where would you find the centromere and kinetochore?
The centromere is a region of a chromosome that holds sister chromatids together, typically located near the center of the chromosome. The kinetochore is a protein structure located at the centromere that attaches the chromosome to spindle fibers during cell division.
Distinguish between kinetochore fibers and polar fibers?
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
Fibers in the spindle that attach to the centromere of the chromosomes?
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
What is a function of those spindle microtubules that do not attach to kinetochores?
microtubules attached to a chromosome Wiki Answers respondents need to start answering questions with a greater sense of purpose. People do not ask questions to receive a terse, slightly correct answer. They want a valid answer to a valid question. As per this one, kinetochore microtubules are NOT just microtubules attached to a chromosome. They are microtubules attached to kinetochores on the centromeres of chromatids. Two chromatids make up a "chromosome" and each chromatid has a centromere with a kinetochore on it. When microtubules from the spindle pole attach to the kinetochores on each side of the "chromosome" the two kinetochore microtubules (from opposite poles of the cell) successfully pull the "chromosome" apart and provide each new developing daughter cell nucleus with a chromatid from that chromatid pair.
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.
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.
Where would you find the centromere and kinetochore?
The centromere is a region of a chromosome that holds sister chromatids together, typically located near the center of the chromosome. The kinetochore is a protein structure located at the centromere that attaches the chromosome to spindle fibers during cell division.
Distinguish between kinetochore fibers and polar fibers?
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
What is the kinetichore?
Kinetochores are proteinaceous region adjacent to the centromere of a sister chromatid pair Kinetochores do the interacting with the mitotic spindles The mitotic spindles with which kinetochores interact are called kinetochore microtubules
A protein structure that is responsible for moving the chromosome along the microtubule?
The kinetochore is the protein structure responsible for moving the chromosome along the microtubule during cell division. It serves as the attachment site for microtubules and helps pull the chromosomes apart. The kinetochore plays a crucial role in ensuring accurate segregation of chromosomes during cell division.
Cellular structure to which the chromosomes attach?
Centromere. It is a region on a chromosome where the kinetochore forms, allowing for attachment to spindle fibers during cell division, ensuring proper segregation of chromosomes.
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
What type of fibers help separate the chromosomes?
Microtubules, specifically kinetochore microtubules, help to separate chromosomes during cell division by attaching to the kinetochore protein complexes on the chromosomes and exerting forces that pull them apart. These microtubules are part of the cell's cytoskeleton and play a crucial role in ensuring accurate chromosome segregation.
Fibers in the spindle that attach to the centromere of the chromosomes?
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
