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...
Mitosis is a fundamental process by which a eukaryotic cell duplicates its genetic material (DNA) and divides to form two daughter cells. These daughter cells are genetically identical to the parent cell and possess the same number of chromosomes. What are the key features of mitosis?
