Erythromycin is an antibiotic that prevents the tRNA molecule from moving from the A site to the P site on the rRNA complex during translation in bacterial ribosomes. Predict the effects of this drug on protein synthesis
What will be an ideal response?
Translation is the process in which the tRNA molecule acts as a translator. The function of tRNA is to pick up a specific amino acid from the cytosol and transfer it to the growing polypeptide chain at the ribosome. Since erythromycin prevents tRNA molecule movement from an A site to a P site, the process of elongation is inhibited. The elongation cycle is when the peptide chain gains an animo acid and the ribosome shifts to the next mRNA codon. As a result of this drug, the polypeptide chain will not be made by bacterial ribosomes.
