Amino-Acyl-TRNA Synthetases Catalyze the Reaction of A

Amino-acyl-tRNA synthetases catalyze the reaction of a:

A) specific amino acid attachment to the 3'-OH at the 3'-CCA of a specific tRNA.
B) specific amino acid attachment to the 5'-OH at the 5'-CCA of a specific tRNA.
C) specific tRNA with ATP to form a so called "charged tRNA" that interacts with a specific site on mRNA.
D) all of the above.
E) none of the above.
