Visualizing DNA

In this experience we have been able to see DNA with a naked eye, i.e, without any kind of instrument. Even though, the quantity of DNA it has not been very high, at the end of the experiment we have got a whitish mass, the DNA from the cells of our buccal mucose, obtained simply rising mouth out.

As you can see in the video, we use different everyday products so as to break the membranes and let the exit of DNA from the nucleous of cells.

It is very easy! you can do it even at home!
