Protein synthesis — practice question

Ricin is a toxic protein that makes ribosomes inactive. What effect will this have on protein synthesis?

  • AAmino acids will be unable to bind to the binding sites on specific tRNA molecules.
  • BAnticodons on mRNA molecules will not base pair to codons on tRNA molecules.
  • CPeptide bonds will not form between adjacent amino acids in the growing polypeptide.
  • DRNA nucleotides will be unable to join by condensation reactions to form rRNA.
