What is the primary role of tRNA molecules during the elongation stage of protein translation?
Answer and explanation
Correct answer: B. Delivering specific amino acids to the ribosome based on codon-anticodon pairing
- Step 1: Define the physiological function of transfer RNA (tRNA).
- Step 2: Each tRNA is charged with a specific amino acid at its 3' acceptor stem and recognizes the corresponding mRNA codon via its complementary three-base anticodon loop.
Answer
Delivering specific amino acids to the ribosome based on codon-anticodon pairing.
Why not the others: mRNA carries genetic blueprints; snRNAs/spliceosomes catalyze intron splicing; nucleoporins form nuclear pores.
