The basic building block of DNA is the nucleotide. The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.Cytosine and thymine are pyrimidine bases, while adenine and guanine are purine bases.The sugar and the base together are called a nucleoside.he nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.
The Chemical Structure of DNA. DNA is a linear polymer, which means it is a chain of units, or monomers. The monomers of DNA are called nucleotides. Each nucleotide contains a phosphate, a sugar, and a base.There are four nucleotide types, identical except for the base.he Chemical Structure of DNA.
