Rna and proteins combine in cells to form structures called ribosomes. ribosomes contain the enzyme active site for peptide bond formation. based on their chemical structures, do you think protein or rna molecules actually form the active site within the ribosome?

a) it could be either, because both molecules have catalytic properties.
b) protein, because only proteins can catalyze a reaction that involves another protein
c) rna, because proteins cannot catalyze a reaction that involves another protein
d) protein, because rna cannot catalyze reactions
