tRNAs carrying the correct amino acid recognize the proper codons on the mRNA because
A. the anticodon of the tRNA hydrogen binds to the codon of the mRNA by complementary base pairing.
B. the codon of the mRNA binds the correct amino acid, and the tRNA stabilizes this interaction.
C. the codon of the tRNA binds to the anticodon of the ribosome by complementary base pairing.
D. the amino acid binds to the anticodon of the mRNA and brings the correct tRNA with it.
