Q. Which of the following inhibits protein synthesis by binding to ribosome?

Solution:

Erythromycin and other macrolide antibiotics inhibit protein synthesis by binding to the molecule (in the subunit) of the bacterial ribosome blocking the exit of the growing peptide chain. The association between erythromycin and the ribosome is reversible and takes place only when the subunit is free from molecules bearing nascent peptide chains.
