If one amino acid out of 574 amino acids is replaced by another in a hemoglobin molecule it will lose following properties, EXCEPT:
Correct answer: D. Quaternary level
- A. Shape
- B. Functional capacity
- C. Oxygen carrying capacity
- D. Quaternary level
Explanation
By changing sequence of amino acids in a quaternary protein the structure and function of proteins is changed but it will remain a new protein of quaternary level. If one amino acid out of 574 amino acids is replaced by another in a hemoglobin molecule, it will lose its quaternary level.The quaternary level of a protein refers to the association of multiple protein subunits to form a multimeric protein. Hemoglobin is a quaternary protein, meaning that it is made up of four subunits. The quaternary structure of hemoglobin is important for its ability to bind oxygen.

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.
