Which of the following does not contain phosphodiester bond?
Correct answer: B. ATP
- A. DNA
- B. ATP
- C. RNA
- D. NAD
Explanation
ATP is a single nucleotide. Phosphodiester bond is present between nucleotides. Adenosine triphosphate (ATP) is a molecule that serves as the primary energy currency in cells. It is a nucleotide that plays a crucial role in the transfer and storage of energy for various cellular processes. ATP is composed of three phosphate groups, a ribose sugar molecule, and an adenine base. The three phosphate groups are linked together, and the energy stored in the high-energy phosphate bonds is what makes ATP an energy carrier. ATP is often referred to as the "energy currency" of the cell because it stores and releases energy to power various cellular activities. The energy is stored in the form of chemical potential energy within the phosphate bonds.

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.
