Question

specific amino acids are attached to trna molecules by
multiple choice
anticodons.
hydrogen bonds.
aminoacyl - trna synthetases.
initiation factors.
deactivating enzymes.

Explanation:

Aminoacyl - tRNA synthetases are enzymes that catalyze the attachment of specific amino acids to their corresponding tRNA molecules. Anticodons are on tRNA for base - pairing with mRNA, hydrogen bonds are for base - pairing interactions, initiation factors are involved in translation initiation, and deactivating enzymes are not related to this attachment process.

Answer:

C. aminoacyl - tRNA synthetases
