The centromere is a specialized constricted region on a chromosome that plays a critical role in cell division (mitosis and meiosis). It acts like a control center, coordinating the movement and separation of sister chromatids during cell division. What are the key features of a centromere?

Chromatides are the two identical copies of a chromosome that are joined together at a specific region called the centromere after DNA replication during cell division (mitosis or meiosis). They represent the sister copies of the genetic information contained within a single chromosome. What are the...
