Tetracycline inhibits protein synthesis by?: (A) Inhibiting initiation and causing misreading of mRNA, (B) Binding to 30 S subunit and inhibits binding of aminoacyltRNA, (C) Inhibiting peptidyltransferase activity, (D) Inhibiting translocation
Answer is B. Ans. is 'b' i.e., Binding to 30 S subunit and inhibits binding of aminoacyl tRNA Tetracycline interact with small ribosomal subunits, blocking access of aminoacyl- tRNA to the mRNA-ribosome complex.
