BIOMOLECULES AND ENZYMES

Detailed explanation-1: -DNA is a polymer of nucleotides which are linked to each other by 3-5 phosphodiester bond.

Detailed explanation-2: -Nucleic acids are polymers of nucleotides joined by covalent (phosphodiester) bonds formed between their sugar and phosphate groups.

Detailed explanation-3: -DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.

Detailed explanation-4: -Phosphodiesters. A phosphodiester bond occurs when two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. Phosphodiester bonds are central to all life on Earth, [fn 1] as they make up the backbone of the strands of nucleic acid.

Detailed explanation-5: -Answer and Explanation: Nucleotides are held together by phosphodiester bonds. Phosphodiester bonds are formed by the condensation of the 3’ OH group of a sugar on one nucleotide to the 5’ phosphate group of the next nucleotide.
