• 1. Consider the three major classes of biologically important molecules: proteins, lipids, and nucleic acids. Which steps of the miniprep procedure act on proteins? on lipids? on nucleic acids?
• 2. Which aspect of plasmid DNA structure allows it to renature efficiently in step 8?
• 3. What other kinds of molecules, in addition to plasmid DNA, would you expect to be present in the final miniprep sample?? How could you find out?
