DNA

Hi and welcome to my blog. I'm a NYC student taking regents and today in science class we saw our DNA. The procedure that we did it in was very easy.
1) We gargle with salt water (it was really disgusting) for 30 seconds.
2) We spit the saliva/salt water solution back in the cup and then gentle put it in a test tube.
3) With a medicine dropper we put in 3 drops of soap solution and stirred it for 1-2 minutes.
4) Then we measured out 20ml of alcohol and very gently pour it.
5) Finally after we wait a little while we can see our dna.
It was so cool.
