The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore.Centromeres were first thought to be genetic loci that direct the behavior of chromosomes.
On the basis of the location of the centromere, chromosomes are classified into four types: metacentric, submetacentric, acrocentric, and telocentric. As previously mentioned, the centromere is easily visualized as the most constricted region of a condensed mitotic chromosome.
