WebA DNA molecule is made up of multiple nucleotides that are connected by phosphodiester bonds. A nucleotide consists of a phosphate group, a pentose sugar (deoxyribose in DNA), and a nitrogenous base. The phosphodiester bond occurs between the phosphate group of one nucleotide and the hydroxyl group of the adjacent nucleotide.
