The Structure and Sequence of DNA

Nucleotide Structure

Nucleotide Structure

Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base. The sugar is deoxyribose in DNA and ribose in RNA. In their mononucleotide form, nucleotides can have one, two , or three phosphates attached to them. When linked together in polynucleotide chains, the nucleotides always have just one phosphate. A molecule with just a nitrogenous base and a sugar is known as a nucleoside. Once at least one phosphate is covalently attached, it is known as a nucleotide.
