The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Transfer RNA (tRNA) acts as an adaptor molecule deciphering mRNA codons during ribosomal protein translation.
Step 2: Detailed Explanation:
In the cloverleaf secondary structure of Transfer RNA (tRNA):
- The Anticodon Loop contains a specific trinucleotide sequence (the anticodon) that base-pairs in an antiparallel orientation with the complementary triplet codon on the messenger RNA (mRNA) during translation.
- The 3' CCA terminal end of the same tRNA molecule is esterified with the corresponding cognate amino acid.
Step 3: Final Answer:
Thus, the anticodon is present in tRNA, corresponding to option (C).
