Explanation:

Tetracycline is an antibiotic that inhibits protein synthesis. Specifically, it blocks the attachment of aminoacyl - tRNA (transfer RNA carrying amino acids) on the A (acceptor) site of the ribosome during the process of translation (protein synthesis). So the first blank should be "protein" and the second blank should be "aminoacyl - tRNA" (or "tRNA" in a more simplified context, but the precise term is aminoacyl - tRNA as it is the tRNA molecule carrying the amino acid that attaches to the A site).

Answer:

First blank: protein; Second blank: aminoacyl - tRNA (or tRNA)
