how to see your dna

You can see your own DNA with a few simple steps. You can watch this video to let Brian Cox explain it to you, but it might get taken down from Youtube again so I’ll explain it here.

First you need to get some of your cells, a good spot is from the inside of your mouth because your cheeks slough off a good amount of cells frequently. Now break off some of those cells by swirling your tongue around and then spit into a tube or beaker. Next, add the liquid soap to break open the cells and get the DNA out. Then add a little salt to encourage molecules and proteins to clump together. Now, add the alcohol, pour it down the side and you will start to see the DNA precipitating out of the solution because it is insoluble in alcohol. It will appear as little white strands. That’s your DNA! All the information needed to make you!
