12) The function of peptide bond :-
(b) To join the amino group of one amino acid to the carboxyl group of another amino acid.
The peptide bond is responsible for the primary structure of protein in which the amino acids are joined by the peptide bonds. The peptide bond is a type of covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid.
The other options are incorrect since :-
• The secondary structure of protein is held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another. So option (a) is incorrect.
• Peptide bond is not responsible for tertiary structure of protein. Four types of bonding are responsible for tertiary structure of protein and they are :- hydrogen bonding, ionic bridges, disulfide bonds, and hydrophobic intermolecular interactions. So option (c) is incorrect.
• The phosphate group attached to the 5' carbon of the sugar on one nucleotide forms a phosphodiester bond with the hydroxyl group attached to the 3′ carbon of the sugar on the next nucleotide. So option (d) is also incorrect.
Since all other options are incorrect except (b).
Thus the correct answer is (b) To join the amino group of one amino acid to the carboxyl group of another amino acid.

Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...
