Individual amino acids are attached to their corresponding tRNAs:
A) through an ester linkage to the 3'-OH in the acceptor stem.
B) through an amide linkage to the anticodon loop.
C) through an amide linkage to the adenine ring at the 3'end of the tRNA.
D) through a phosphoester linkage to the 5' end of the tRNA.
E) None of the above.

Question

Quizplus · Accepted Answer

Amino acids are attached to tRNAs through the 3'-OH group of the acceptor stem, which forms an ester bond with the carboxyl group of the amino acid. This process is catalyzed by enzymes called aminoacyl-tRNA synthetases. The anticodon loop and adenine ring of the tRNA are not involved in this process.
