Bio 115, spring 2005 Problem set #6 - 1 - 1. You have prepared an antibody that recognizes the 5' cap of human mRNAs with a high affinity. You prepare a cell lysate and perform an immunoprecipitation. What sorts of molecules are likely to be present in the immunoprecipitate? 2. How is the 5' cap important for mRNA stability? For translation? 3. Where in the cell does capping of mRNAs occur? 4. What protein(s) binds the 3' end of mRNAs? 5. Besides alternative splicing, how can a mRNA be used to generate multiple different proteins? 6. What are some of the major differences between translation in prokaryotes and eukaryotes? 7. What are some of the energy dependent steps in translation?

Bio 115, spring 2005 Problem set #6 - 2 - 8. How do eukaryotes determine where to initiate translation? How can this be proved experimentally? 9. How does the peptidyl transferase reaction of translation procede? In particular, a) does protein synthesis procede from the amino-terminus or carboxy-terminus of the protein?
