Chromatid
A chromatid is one of two identical strands of DNA making up a chromosome that are joined at their   centromeres, for the process of nuclear division (mitosis or meiosis). The term is used so long as the centromeres remain in contact. When they separate (during anaphase of mitosis and anaphase 2 of meiosis), the strands are called daughter-chromosomes.The tips of the chromatid are called telomeres.They are there to prevent the ends of the chromosome from attaching to other chromosomes. It has been said that after repeated cell replication, the telomeres gets shorter resulting in cell death. This means that the way telomeres work could determine the lifespan of a cell. However this has not been proven.
