How does tRNA get charged with the correct amino acid?
a. The ribosomes add the correct amino acids to the tRNA when the tRNA is in the ribosomal A site.
b. The codon on the mRNA adds the correct amino acid to each tRNA by complementary base pairing.
c. The anticodon on the tRNA fits specifically to each type of amino acid, so all that is needed is one type of chargase for all the types of tRNA.
d. The matching tRNA synthetase adds the correct amino acid.
