WebFor the DNA molecule, there are four nitrogenous bases that are incorporated into the standard DNA structure. These include the Purines: Adenine (A) and Guanine (G), and the Pyrimidines: Cytosine (C) and Thymine (T). RNA uses the same nitrogenous bases as DNA, except for Thymine. Thymine is replaced with Uracil (U) in the RNA structure. WebJul 20, 1998 · Each strand of a DNA molecule is composed of a long chain of monomer nucleotides.
