The equal apportionment of daughter chromosomes to each of the two cells resulting from cell division is chromosome segregation . Chromosome segregation occurs during mitosis and meiosis . Segregation and division are regulated by DNA replication .
Centromeres are critical for segregation.
Centromere structures vary among organisms. Centromeres are the attachment points of kinetochores . Molecular motors attached to kinetochores move chromosomes in segregation. Centromeres and telomeres are required in the replication and segregation of nuclear chromosomes. Special considerations apply to the replication of non-nuclear genetic material.
