Which of the following chemical characteristics is not common to all living beings?
Correct answer: C. Type of protein present in the body
- A. Similar triplet code for amino acids
- B. Energy is stored by high phosphate bonds
- C. Type of protein present in the body
- D. Ribosomes are the sites of protein synthesis
Explanation
This is the correct answer. The type of proteins present in the body can vary among different organisms. While the basic structure of proteins is conserved, specific proteins can differ across species. The correct answer is C (Type of Protein Present in the Body). The specific proteins present in the body can vary among different living beings, reflecting their unique genetic makeup and functional adaptations.

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.
