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.
Nucleotides. Both DNA and RNA are nucleic acids, and are polymers of nucleotides. A nucleotide has three components: a pentose (five-carbon sugar), and attached to different parts of it a phosphate group and a nitrogenous base (either a purine or a pyrimidine).he monomers of DNA are deoxyribonucleotides, because their sugar is deoxyribose. The nucleotides in a nucleic acid are not all identical. There are four kinds in each nucleic acid, differing only in their bases. The bases in the nucleotides of RNA are cytosine, uracil, adenine, and guanine.
