Detailed explanation-1: -DNA is a polymer of nucleotides which are linked to each other by 3-5 phosphodiester bond.
Detailed explanation-2: -The bond joining two successive nucleotides in the same strand of DNA is called the phosphodiester bond. the phosphodiester bond is the linkage between the 3’ carbon atom of one sugar molecule and the 5’ carbon atom of another, deoxyribose in DNA and ribose in RNA.
Detailed explanation-3: -Adjacent nucleotides of a single strand of DNA are joined by covalent bonds called phosphodiester bonds.
Detailed explanation-4: -Another way of defining the phosphodiester bond is that it is formed between any two adjacent nucleotides in a nucleic acid in which 5’ and 3’ hydroxyls of two adjacent sugars form a double ester with phosphoric acid.
Detailed explanation-5: -A phosphodiester bond is a covalent bond between phosphate and 2 sugars (hydroxyl groups). A covalent bond involves the sharing of a pair of electrons.
