However, it is unclear …
WebMitotic spindles are self-organized structures constructed from dynamic microtubules, which faithfully segregate chromosomes to newly formed daughter cells. Errors in this process lead to wrong copy numbers of chromosomes (aneuploidy), which is detrimental for the organism. Aneuploidy is a hallmark for cancer. Chromosome separation is mainly …
