Explanation:
Detailed explanation-1: -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-2: -Nucleic acids (i.e., DNA and RNA) are made up of nucleotide monomers linked via phosphodiester bonds. Each nucleotide consists of a phosphate group, a sugar group (deoxyribose for DNA; ribose for RNA), and a nitrogenous base.
