a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
The most highly repeated sequences found so far in mammals are called "satellite DNA" because their unusual composition allows them to be easily separated from other DNA. These sequences are associated with chromosome structure and are found at the centromeres (or centers) and telomeres (ends) of chromosomes.
