Which one of the following statements is correct in the context of erythromycin- mediated inhibition of protein synthesis in bacteria?
1
Erythromycin inhibits protein synthesis at the step of elongation, but it nonetheless allows translation of the first few codons.
2
Erythromycin inhibits protein synthesis at the step of elongation, and it prevents formation of even the first peptide bond.
3
Erythromycin inhibits formation of the translation initiation complex.
4
Erythromycin is toxic to bacteria because it results in initiation of protein synthesis with elongator tRNAs.
