5. You are given three different substances that are known mutagens. Using a variety of techniques, you analyze the results of exposure to these substances. Your findings are shown in the table below. Using this data, match each of the three substances with one of the following molecular properties and explain your choice. Molecular Properties I. One mutagen that looks like cytosine but forms a covalent bond with guanine One mutagen that can bind with either adenine or guanine II. III. A molecule that can insert itself between two base pairs in a DNA strand Substance A B C A Result of exposure Increases the number of mutants that produce mRNA with AGA codons instead of AAA codons Substance Molecular property B Significantly fewer viable colonies Increase in mutants containing frameshift mutations Reason for choice

Below is an EMSA showing four different reactions, A-D. In each tube there is some combination of labelled DNA probe, Protein X (the protein you are studying), and an antibody for Protein X. Identify which combination of components are found in each of the four reactions and explain how you determined that based on the molecular interactions being studied and your knowledge of gel electrophoresis. It is possible that multiple lanes have the same component(s). A B C D EMSA
