A chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain... Full article >>>.
A chromosome is a DNA molecule with part or all of the genetic material 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 in an X-shaped structure. The original chromosome and the copy are now called sister chromatids. During metaphase the X-shape structure is called a metaphase chromosome.
