Lab #3-Meghan Wright Exercise #1 Exercise #2 1. Nile Blue A can stain DNA and is easier to see because it uses only visible light and it doesn’t require destaining. It is an alternative to Methylene blue stain for classroom use. 2. Methylene blue is also non-toxic and is also commonly found in classrooms to stain DNA but requires an extensive destaining process. 3. Ethidium bromide is normally used in laboratories and is toxic because it breaks down into carcinogens and potent mutagens. Exercise #3
