A chromosome (from ancient Greek: ÏÏÏÎ¼ÏÏÏÎ¼Î±, chromosoma, chroma means color, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism. Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division. Before this happens, every chromosome is copied once , and the copy is joined to the original by a centromere, resulting either in an X-shaped structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends.
