Which of the following type of RNA is catalytic in nature?
Correct answer: D. Ribozyme
- A. tRNA
- B. rRNA
- C. mRNA
- D. Ribozyme
Explanation
Option D (Ribozyme) is correct because ribozymes are RNA molecules capable of catalyzing biochemical reactions, akin to protein enzymes. This property highlights RNA's versatility in biology. In contrast, tRNA, rRNA, and mRNA serve primarily structural or informational roles in protein synthesis and lack catalytic activity.

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.
