| Video Discription | Chromosome segregation is the process in eukaryotes by which two sister chromatids formed as a consequence of DNA replication, or paired homologous chromosomes, separate from each other and migrate to opposite poles of the nucleus The process is very important because the cell has to ensure that exactly one set of duplicated chromosomes is transferred to each of the two cells produced during cell division. The cell stage when chromosomes are segregated is known as ‘mitosis’, which is further subdivided into prophase, metaphase, and anaphase. During an early stage of mitosis known as ‘prophase’, protein complexes known as condensins interact with chromosomes and facilitate chromosome condensation or compacting. The two sister chromatids produced after replication are held together by specialized proteins known as cohesins. During ‘metaphase’, the chromosomes then align at the metaphase plate and are captured by microtubules emanating from the spindle, which attach to the kinetochore that forms on each sister centromere. After all chromosomes are captured, the cohesin is degraded and one complement of chromosomes are pulled by the microtubules into each of the dividing daughter cell in a cell stage known as ‘anaphase’.
