In the first experiment there was no cleavage (no breakdown from polymer into monomer) because the enzyme is what does this work and if no enzyme is present then no cleavage can happen. In the second experiment there is a high rate of cleavage because the enzyme does this job and the enzyme is present in experiment 2. In the third experiment the enzyme is heated. This denatures the enzyme so that it cannot bind to the substrate and cleave. In the forth experiment there is no cleavage that occurs when the enzyme is present with the dipeptide that was synthesized. This means that the dipeptide does indeed work as an inhibitor of the enzyme. In the fifth experiment the RNA does not appear to inhibit the function of the enzyme as seen by the data that shows the cleavage rate is very close to the rate of cleavage in experiment 2.
