Concept introduction: A nucleotide refers to a basic DNA building block and structural unit. It contains a five-sided sugar, a phosphate group and a nitrogenous base. The nucleotides join together to form a chain of DNA. The nucleotides of DNA and RNA are linked covalently by bridges of the phosphate group. A phosphodiester linkage joins the
