Chromosomes stop moving towards the pole
WebFeb 24, 2014 · In telophase, the separated chromosomes arrive at opposite poles. The remainder of the typical telophase events may or may not occur, depending on the species. In some organisms, the chromosomes decondense and nuclear envelopes form around the chromatids in telophase I. WebChromosomes selectively detach at one pole and quickly move towards the opposite pole when kinetochore microtubules are depolymerized in Mesostoma ehrenbergii …

During telophase, the chromosomes reach the poles and new nuclear … WebIn anaphase, the connection between the sister chromatids breaks down, and the microtubules pull the chromosomes toward opposite poles. During metaphase, all the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell.
WebThis shows that the chromosomes “eat” their way along the kinetochore microtubules toward the pole. In these cells, subunit flux accounts for only 20% to 30% of chromosome movement during anaphase A, and this flux is dispensable for chromosome movement. WebApr 23, 2024 · Chromosomes move in a random way until they attach, from both sides of their centromeres to polar fibers. Chromosomes align at the metaphase plate at right angles to the spindle poles, and are held there by the equal forces of the polar fibers exerting pressure on the chromosomes' centromeres.
WebDec 30, 2024 · Somewhat perversely, even as the chromosomes move towards the spindle poles, the poles themselves move outward slightly. Separation of the sister chromatids requires the dissociation of the molecular “glue” holding them together: the cohesin proteins.
