1) What is the texture and consistency of the DNA?

2. Why did we use a salt in the extraction solution?

3.            Is the DNA soluble in the aqueous solution or alcohol?

4.            What else might be in the ethanol/aqueous interface? How could you eliminate this?

5.            Which DNA bases pair with each other? How many hydrogen bonds are shared by each pair?

6.            How is information to make proteins passed on through generations?

7.            Watch the Virtual Lab demonstrating DNA Extraction (located in the Student Portal and/or your lab introduction). In this experiment, how do the Lysis Solution and the Salt Solution vary by function?

8.            Identify one step which was included in the Virtual Lab which was not required in the hands-on experiment. Then, identify one step which was included in the hands-on experiment, but not the virtual lab. Why weren’t these steps required?
