Question

Which of the following bond is not related to nucleic acid?

• A. H-bond
• B. Ester bond
• C. Glycosidic bond
• D. Peptide bond

Answer 1

Answer: (D)

Peptide bond

A peptide bond is not related to nucleic acid. A peptide bond is a covalent chemical bond formed between two amino acid molecules. The peptide bond is synthesized when the carboxyl group of one amino acid molecule reacts with the amino group of the other amino acid molecule, causing the release of a molecule of water, hence the process is a dehydration synthesis reaction also known as a condensation reaction.

So, the correct answer is option D.
