A polynucleotide is a nucleic acid molecule consisting of a long chain of nucleotides. Nucleotides in a polynucleotide molecule are held together by a bond between the phosphate group of one nucleotide and the sugar of a second nucleotide, which is called a phosphodiester bond.
The hydroxyl group attached to the 3â carbon of the second nucleotide is also lost. The linkage between the nucleotides in a polynucleotide is called a phosphodiester bond, âphospho-â indicating the presence of a phos-phorus atom and âdiesterâ referring to the two ester (CâOâP) bonds in each linkage.
