Question

question 32 1 pts in bacteria, the antibiotic tetracycline blocks the site where trna molecules enter the ribosome. the most likely reason that bacteria die from treatment with tetracycline is because the antibiotic causes the trna molecules to randomly arrange into proteins that do not function. prevents the bacteria from assembling essential proteins. inhibits the cell from producing the mrna. causes trna rather than mrna to be made into proteins.

Explanation:

Translation is the process of protein synthesis in cells. tRNA brings amino acids to the ribosome. If tetracycline blocks the site where tRNA enters the ribosome, amino acids cannot be added to the growing polypeptide chain. Proteins are essential for bacterial survival (e.g., enzymes for metabolism, structural proteins). Without proper protein assembly (due to lack of tRNA - mediated amino - acid delivery), bacteria cannot function and die.

• The first option is wrong because tRNA doesn't randomly arrange into proteins. tRNA has a specific role in bringing amino acids based on mRNA codons.
• The third option is wrong because tetracycline acts on the ribosome (translation site), not on mRNA production (transcription).
• The fourth option is wrong because mRNA is the template for protein synthesis, not tRNA. tRNA is just the carrier of amino acids.

Answer:

pre - vents the bacteria from assembling essential proteins.
