Which feature of tRNA ensures correct amino-acid placement during translation?
- A
Anticodons recognize the ribosome's E-site directly.
- B
Random recruitment of any amino acid by the A-site.
- C
tRNA reads mRNA 5' to 3' as DNA polymerase does.
- Dcheck_circle
Specific anticodon-codon base pairing on mRNA, with cognate amino acid attached at the 3' CCA end.
Explanation
Each tRNA has an anticodon that base-pairs with a complementary mRNA codon and carries the corresponding amino acid (charged by aminoacyl-tRNA synthetase) at its 3' CCA end, providing translation fidelity.
