Visible in prophase and attach to spindle fibers in meta phase
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region 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.
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.
Spindle fibers attach to chromosomes during metaphase of mitosis. Special protein structures called kinetochores on the chromosomes interact with the spindle fibers to ensure proper alignment and segregation of the chromosomes during cell division.
The stage when spindle fibers attach to chromosomes is during metaphase of mitosis or meiosis. Spindle fibers, which are made of microtubules, attach to the centromere region of chromosomes to help separate them correctly during cell division.
chromosomes attach to spindle fibers
The phase of mitosis when chromosomes attach to the spindle fibers is the metaphase. During metaphase, the chromosomes align along the equatorial plane of the cell before being separated and pulled to opposite poles during anaphase.
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
That would be during metaphase in mitosis and the chromosomes attach to the spindle fibers because each half of the chromosomes need to migrate to the opposite poles. The spindle fibers are temporary but aid in the movement of the chromosomes.
Spindle fibers attach to chromosomes by binding to specific protein structures called kinetochores located on the centromere of each chromosome. The spindle fibers then exert tension on the chromosomes, aligning them along the cell's equator during cell division.
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.
