2. Does your protein contain any subunits? How might you represent that in your model? 3. How does your assigned mutation affect the protein's structure? Decide if you will build one model showing where the mutation occurs or if you would prefer to build 2 separate models (one model for the normal protein and one model for the mutated protein. 4. How does your assigned mutation affect the protein's function? How does it impact the function of the cell and the function of the organism? 5. Identify where the mutated amino acid is located within your protein. Think of how you can represent this in your model. 6. Evaluate the limitations of the model - what is it about your model that is not representative of the actual protein as it is found in an organism?

What is the effect of your mutation on the protein produced by the mutant gene? According to the Wobble hypothesis, a base in the third position of a codon can form non-standard base pairing. Therefore, there may be no effect on the protein produced. Describe a detailed model of how the mutation described in question might alter the function of the protein and lead to the phenotype of your mutant. When answering this question, consider the functional domains of the HSF protein. Describe at least two experiments that could be done to test the model described above. When answering this question, consider utilizing the HSF GFP expression plasmid you have generated.

Mutations in the genes encoding collagens often have detrimental consequences, resulting in severely crippling diseases. Particularly devastating are mutations that change glycines, which are required at every third position in the collagen polypeptide chain so that it can assemble into the characteristic triple-helical rod (see Figure 20-9). A. Would you expect collagen mutations to be detrimental if only one of the two copies of a collagen gene is defective? B. A puzzling observation is that the change of a glycine residue into another amino acid is most detrimental if it occurs toward the amino terminus of the rod-forming domain. Suggest an explanation for this.
a. Mutations in DNA can affect the peptide product that is being coded. Below is a wild type gene along with a series of mutations of that same gene. Determine the type of mutation as well as how it affects the final peptide sequence. b. What mutations would have the greatest effect on peptide sequence? Which would have the least effect? Why?
