<prompt> Tetracycline inhibits protein synthesis by ?Inhibiting initiation and causing misreading of mRNABinding to 30 S subunit and inhibits binding of aminoacyl tRNAInhibiting peptidyl transferase activityInhibiting translocation  <response>: Ans. is b i.e., Binding to 30S Subunit and inhibits binding of aminoacyl tRNA o Tetracycline interact with small ribosomal subunits, blocking access of aminoacyl- tRNA to the mRNA-ribosome complex. o Tetracyclines bind to 30 S subunit of ribosome.
