All humans start out as a single cell and grow into trillions of cells. DNA tells the single cell to divide into two cells, then four, then eight until a whole body forms. It controls the growth of EVERYTHING, from your head to your toes.

DNA also influences many individual traits, such as whether you are a boy or a girl and whether you are tall or short.
