Which of the followings sugars is/are component of nucleic acid?
Correct answer: C. Pentoses
- A. Tetroses
- B. Trioses
- C. Pentoses
- D. Hexoses
Explanation
The fundamental building block of nucleic acids is the nucleotide, which comprises three components: a phosphate group, a nitrogenous base, and a pentose sugar. Pentoses, such as ribose in RNA and deoxyribose in DNA, are integral to the structure of nucleic acids. Tetroses and trioses are not involved in the structure of nucleic acids; they serve as intermediates in various metabolic pathways. Hexoses, although critical in energy metabolism, do not form part of nucleic acid structures.

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.
