A) You are very interested in PKU, and you decide that you want to know more about it. You have decided that the best way to do this would be to study the biochemical pathways that underlie phenylalanine synthesis/metabolism in a model organism (not human). You can use any organism that you would like (prokaryote or eukaryote). Design a set of experiments to look at this biochemical pathway or the signaling pathways that regulate it in greater detail. You can use any variety of genetic screens or tests, but you should describe how you might find new genes associated with this pathway (new enzymes or regulatory molecules). Describe how you would determine how many genes that you have identified, and how you might determine their relationship to the pathway. Be specific. 
B) What results might you expect if you were going to run this experiment? 
ie. Will my experiment pick up recessive phenotypes?, dominant phenotype? epistatic relationships? How might you test if these results are statistically significant? 
C) If you chose (eukaryote/prokaryote), what advantages might be available had you chosen the other system (prokaryote/eukaryote)?
