The kinesin-14 motors are evolutionarily conserved minus-end-directed kinesin motors that occur in diverse organisms from simple yeasts to higher eukaryotes.
WebThe aim of the mitotic process is to segregate the genetic material packed into duplicated chromosomes equally between two daughter cells. To accomplish this, cells form a highly dynamic yet robust structure called the mitotic spindle [1,2,3].In the majority of higher eukaryotes, chromosomes attach to spindle microtubules (MTs) by kinetochores, large … 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 …
