Question

Quizplus · Accepted Answer

Aminoacyl-tRNA synthetases bind to the 3' end of tRNA molecules, specifically to the CCA sequence which is present at the 3' end of all tRNAs. This binding positions the amino acid at the 3' end, which is then ready to be added to the growing polypeptide chain during translation.
