tRNA participates in which cellular process?

tRNA participates in which cellular process?

• A. Participates in DNA replication
• B. Transcribes DNA into RNA
• C. Participates in protein synthesis
• D. Stores energy

Answer: (C)

The main function being tested here is tRNA’s role in translating genetic information into a protein sequence. tRNA delivers specific amino acids to the ribosome during protein synthesis (translation). Each tRNA carries one amino acid and has an anticodon that pairs with the corresponding codon on the mRNA, ensuring the amino acid is added in the correct order to build the growing polypeptide chain. The charging of tRNA with its amino acid is done by aminoacyl-tRNA synthetases, and the actual assembly at the ribosome uses energy from GTP hydrolysis during translation steps. tRNA is not involved in copying DNA, nor in transcription of DNA into RNA, and it does not store energy; those roles belong to other processes and molecules.
