A DNA nucleotide has three parts: a sugar molecule called deoxyribose ; a phosphate group, and a molecule that is referred to as a nitrogenous base because it contains nitrogen atoms. The deoxyribose sugar and the phosphate group are identical in all DNA nucleotides. However, the nitrogenous base may be any one of 4 different kinds.
