Final answer:
The amino acid attaches to the 'Acceptor stem' of the tRNA during charging. Even if a tRNA is chemically modified with a different amino acid, it still recognizes the mRNA codon specified by its original anticodon.
Step-by-step explanation:
To which part of tRNAs would an amino acid attach to during tRNA charging? The correct answer is (d) Acceptor stem.
An amino acid is added to the end of a tRNA molecule through the process of tRNA "charging," during which each tRNA molecule is linked to its correct or cognate amino acid by a group of enzymes called aminoacyl tRNA synthetases. This process occurs at the acceptor stem, which is the 3'-terminal end of the tRNA molecule. The amino acid is covalently bonded to the 3’ end of the tRNA via an ester bond to the hydroxyl group of the adenosine residue at the CCA tail of the tRNA.
41. If a tRNA is chemically modified such that the amino acid bound is different than the one specified by its anticodon, it will still recognize the codon in mRNA specified by its anticodon, answer (a). The anticodon-codon pairing is the mechanism that ensures the correct placement of amino acids during the translation process.
