Monosaccharide found in nucleolus is:
Correct answer: A. Pentose
- A. Pentose
- B. Erythrose
- C. Tetrose
- D. Hexose
Explanation
The correct answer is pentose because ribose, a pentose sugar, is a component of RNA, which is synthesized in the nucleolus. The nucleolus is primarily involved in the production of ribosomes, which requires ribosomal RNA (rRNA). Hence, pentose sugars are integral to the structure of nucleic acids associated with the nucleolus. Erythrose and tetrose refer to sugars with four carbon atoms, which are not involved in nucleic acids. Hexose sugars have six carbon atoms and are primarily involved in energy processes rather than forming nucleic acids found in the nucleolus.

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.
