Which of the following is cloverleaf like structure?
Correct answer: C. tRNA
- A. mRNA
- B. DNA
- C. tRNA
- D. rRNA
Explanation
The correct answer is tRNA. Transfer RNA (tRNA) has a characteristic cloverleaf structure formed by its secondary structure, which includes three loops and an anticodon that pairs with the mRNA codon. This structure is essential for its function in translation, as it brings the correct amino acid to the ribosome during protein synthesis. The other options - mRNA, DNA, and rRNA - have different structures and functions. mRNA is linear and serves as a template for protein synthesis, DNA is a double helix that contains the genetic code, and rRNA is a component of ribosomes without a cloverleaf structure.

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.
