Question

Quizplus · Accepted Answer

Amino acids are transported by their specific tRNAs through the binding of the amino acid to the 3' end of the tRNA molecule. This occurs through the formation of an ester bond between the carboxyl group of the amino acid and the 3' hydroxyl group of the ribose sugar in the tRNA. This is known as aminoacylation or charging of the tRNA.
