WebDuring anaphase, sister chromatids are separated at the centromere and are pulled towards opposite poles of the cell by the mitotic spindle. During telophase, chromosomes arrive at opposite poles and unwind into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears. http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/10Q.html

WebApr 13, 2024 · During cell division, chromosome segregation is considered to be driven by a spindle consisting of microtubules. Firstly, the microtubules capture and align the chromosomes at the spindle center. The chromosomes are segregated and moved to the poles of spindles during anaphase. WebDuring anaphase one, there are homologues that have been positioned on the metaphase plate during the previous phase, metaphase. In anaphase, these homologues are pulled on by the mitotic spindle, being pulled apart. After the homologues are separated, the spindle fibers pull them into opposite poles of the cell.
