Final answer:
Tetracycline binds to the 30S ribosomal subunit of bacterial ribosomes, blocking the association of tRNAs with the ribosome and inhibiting protein synthesis.
Explanation:
Tetracycline binds to the 30S ribosomal subunit of bacterial ribosomes, blocking the association of tRNAs with the ribosome during translation. This action inhibits protein synthesis in bacteria, making tetracyclines effective antibiotics against bacterial infections.
