Question

To which part on tRNAs would an amino acid attach to during tRNA charging?

1) 3′ acceptor arm
2) Anticodon arm
3) TψC arm
4) DHU arm
5) Extra arm

Answer 1

An amino acid attaches to the 3′ acceptor arm, also known as the aminoacyl arm, of the tRNA during tRNA charging.

Step-by-step explanation:

To which part on tRNAs would an amino acid attach during tRNA charging? The amino acid attaches to the 3′ acceptor arm of the tRNA during the charging process. This part of the tRNA is also known as the aminoacyl arm. During tRNA charging, an enzyme known as aminoacyl tRNA synthetase catalyzes the attachment of the amino acid to the tRNA, forming an ester bond with the 3′ hydroxyl group of the terminal adenosine nucleotide found in the CCA sequence at the 3′ end of the tRNA. This charged tRNA is now ready to deliver its amino acid to the growing peptide chain during protein synthesis.
