Class II amino acyl tRNA synthetase transfers the amino acids to the tRNA __________

Class II amino acyl tRNA synthetase transfers the amino acids to the tRNA __________ Correct Answer 2‘-OH of the A base

Class II aminoacyl tRNA synthetase transfers the amino acid to the 2’-OH of the tRNA. There is a quick equilibrium between the 2’ and the 3’-OH. On the other hand class I amino acyl tRNA synthetase transfers it to the 3’-OH.
