Which of the following is wrongly paired?

A. Nucleic acid – hydrogen bond

B. Polysaccharide – glycosidic bond

C. Proteins – peptide bond

D. Phospholipids –phosphate linkage

Explanation: Nucleic acids, that is, DNA and RNA show phosphodiesterase linkage which is the major type of linkage. Without the phosphodiester bonds between the phosphate and adjacent 3’OH sugar molecule, the backbone will not be formed. Therefore, the nucleotides would not be able to attach and bond to form a nucleic acid.
