Best Answer

DNA is composed of a few chemicals. Phosphates and sugars form the upright of the ladder. The steps are made of the four chemicals :Adenine, Guanine, Thymine, Cytosine. Only two chemicals per step. Adenine and thymine always go together, and cytosine and guanine are always together, too. The placement of these bases on each step and the steps as a whole form a code which are the genes.
