Which one of the following correctly matches the nucleic acid molecule with its role? Molecule Role A - VCE - SSCE Biology - Question 1 - 2023 - Paper 1

In this question, we need to identify the nucleic acid molecule that correctly describes its role.

1. Understanding tRNA: Transfer RNA (tRNA) is responsible for transporting specific amino acids to the ribosome during protein synthesis. This role is crucial for translating the genetic information encoded in mRNA into a corresponding sequence of amino acids.

2. Examining the Options:

   • A. DNA: While DNA does carry genetic information, it does not directly interact with ribosomes where protein synthesis occurs.
   • B. tRNA: This option correctly states that tRNA carries amino acids to ribosomes, making it the right answer.
   • C. mRNA: mRNA carries genetic information from DNA to ribosomes but is not a structural component of ribosomes.
   • D. rRNA: Ribosomal RNA (rRNA) is a structural component of the ribosome but does not contain the genetic information that is transcribed.

3. Conclusion: The correct match of the nucleic acid molecule with its role is B. tRNA carries amino acids to ribosomes.
