Human DNA in a Test Tube
There are plenty of illustrations of what the human genome looks like, but the reality is actually quite different. Floating within this test tube is a clump of human DNA. But you don’t need to be a scientist to make DNA visible. Simply add two cups of water to a glass, add a tablespoon of salt and garble for approximately 1 minute. Then spit the water back into the cup, add 2 drops of dish soap and stir. Then add ½ cup of rubbing alcohol and stir for a couple of minutes. And voila! Your DNA becomes visible.
