What is the immediate molecular consequence of tetracycline binding to the bacterial 30S subunit?

Steric blockage of aminoacyl-tRNA entry into the A site, preventing addition of new amino acids to the growing peptide chain.

Permanent cross-linking of ribosomal proteins that leads to ribosome degradation by cellular proteases.

Induction of mRNA cleavage at the decoding site, resulting in prematurely truncated messages that halt translation.

Inhibition of the ribosomal peptidyl transferase center on the 50S subunit, preventing peptide bond formation between amino acids.
