Question

Quizplus · Accepted Answer

The specific amino acids attach to the arm of a tRNA that ends in CCA via an ester bond. This is because the CCA sequence at the 3' end of tRNA serves as the attachment site for amino acids. The amino acid is activated by ATP to form an aminoacyl-AMP intermediate, which then reacts with the 3' hydroxyl group of the ribose sugar of the CCA to form an ester bond between the amino acid and the tRNA.
