Number of amino acids incorporated in beta chains of a molecule of hemoglobin is:
Correct answer: C. 292
- A. 280
- B. 282
- C. 292
- D. 290
Explanation
The correct answer is 292. Hemoglobin is composed of four protein subunits, including two alpha and two beta chains. Each beta chain contains 146 amino acids. Therefore, for two beta chains, the total number of amino acids is 146 x 2 = 292. The other options are incorrect as they do not match this calculation.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
