A chromatid (Greek khrōmat- 'color' + -id) is one half of a duplicated chromosome. Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes. WebA chromosome is made of two sister chromatids (left side vs. right side of the chromosome) fused together at a centromere. During mitosis/meiosis, the chromosome becomes disconnected at the centromere → 2 chromosomes. So think of each chromatid as a developing chromosome that has to mature.
