What should I do if I am having trouble seeing DNA in biology Experiment 7.1?

1. Your blender may not be chopping things fine enough. Put the blender on its highest setting and let it go for a couple of minutes.

2. Mix the solution with the soap for 10 minutes. This will allow more time for the lipids to be destroyed. Also, I have heard several reports that clear liquid hand soap produces EXCELLENT results. You might try that instead of dish soap.

3. Add twice as much meat tenderizer. This will make more protein destruction. 

4. Ideally, you should not mix the alcohol with the rest of the solution at all. If you have to, do not destroy the boundary between the liquids. There should be a distinct alcohol layer above the other liquid.
