Read the statements regarding structure of polynucleotide chain and choose the correct option. 1. A nitrogenous base is linked to the pentose sugar through a phospho-diester linkage. 2. Two nucleotides are linked through 3'-5' N-glycosidic linkage to form a dinucleotide. 3. The polynucleotide backbone is formed by sugar and phosphate. 4. A phosphate group is linked to 5'-OH of a nucleoside through a N- glycosidic linkage to form a nucleotide.
