A pair of chromatids consists of two identical copies of a chromosome that are joined together at a region called the centromere. They are formed during DNA replication in the S phase of the cell cycle and are crucial for ensuring that each daughter cell receives an accurate copy of the genetic material during cell division. Chromatids are referred to as sister chromatids when they are identical and connected, and they separate during mitosis or meiosis to ensure proper distribution of chromosomes.
