Experiment 3: DNA Extraction 1. What is the texture andconsistency of the DNA? 2. Why did we use a salt in the extractionsolution? 3. Is the DNA soluble in the aqueous solution or alcohol?4. What else might be in the ethanol/aqueous interface? How couldyou eliminate this? 5. Which DNA bases pair with each other? Howmany hydrogen bonds are shared by each pair? 6. How is informationto make proteins passed on through generations? 7. Watch theVirtual Lab demonstrating DNA Extraction (located in the StudentPortal and/or your lab introduction). In this experiment, how dothe Lysis Solution and the Salt Solution vary by function? 8.Identify one step which was included in the Virtual Lab which wasnot required in the hands-on experiment. Then, identify one stepwhich was included in the hands-on experiment, but not the virtuallab. Why weren’t these steps required?
