WebFeb 20, 2024 · Phosphodiester Bond is involved in the polymerization of nucleotides. When polymerization occurs, the -OH group gets attached to 3 carbon of nucleotides (sugar molecules) with the phosphate group’s -OH of another nucleotide. Hydrogen and hydroxyl may combine with each other. WebThe phosphodiester bonds that join one DNA nucleotide to another always link the 3’ carbon of the first nucleotide to the 5’ carbon of the second nucleotide.
