Chapter 3.4, Problem 2I
Summary Introduction

To explain: The differences between the peak absorbance of the native (untreated) and reduced (denatured) RNase A.

Introduction: RNase A is an enzyme/ protein that stimulates the catabolism of RNA into micro-molecules. It is a nuclease that has 4 disulfide bridges between the cysteine molecules with an overall length of 124 amino acids. UV spectroscopy is used to measure the intensity of the light that is absorbed by the molecule at different wavelengths.

Summary Introduction

To explain: The changes observed when the protein RNAase A was reoxidized.

Introduction: Proteins when denatured lose their structure and function. Under stimulated conditions a protein can refold again to form the disulfide bridges and other interactions.

Summary Introduction

To conclude: The structure of RNase on the basis of the experiment.

Introduction: RNase A is a nuclease that catalyzes the degradation of the RNA molecules. This reaction is exergonic and will release energy.
