Question

The tertiary structure of a protein molecule results from

• A. Hydrophobic bonding
• B. Electrostatic bonding
• C. Hydrogen bonding
• D. All of these

Answer 1

The correct option is D All of these

The tertiary structure of the protein is a three-dimensional structure. It has a single polypeptide chain backbone with one or more protein secondary structures. The interaction and bonds of the side chain within the particular protein determines its tertiary structure.

Tertiary structure is formed by different types of bonds like hydrophobic bonding, electrostatic bonding, hydrogen bonds, disulphide bonds, ionic interactions, etc.

Hence, the correct answer is 'All of these'.
