DNA molecules are composed of repeating subunits called nucleotides. A nucleotide is made of three parts: a nucleobase, a certain type of sugar (deoxyribose in the case of DNA â¦ nucleotides), and one or more phosphate groups.There are four different nucleobases found in DNA: adenine, cytosine, guanine, and thymine.NA molecules are composed of repeating subunits called nucleotides.
