Me and my DNA
I took this picture last friday in my science lab. haha. Its a picture of me with my DNA. haha. I look like the hugest nerd. Anyways. I am wearing my tube top that I knit last summer. haha I need to start wearing a scarf when I drive. I've been driving with the windows down and my hair looks like a whirl wind when I get to school. I'll never be one of those girls whose hair is perfectly in place. Sigh thats nothing to dwell on.
To see your DNA you'll need:
5ml dish soap solution, a test tube, 10ml saline, a dixie cup, and 10ml rubbing alchohol
saline solution=Prepare the 0.9 percent salt solution (2 teespoons of table salt dissolved in 1 quart/liter of water)
soap soultion=1 volume of detergent mixed with 3 volumes of water
Pour amount of saline into a dixie cup
Swish the saline around in your mouth for 30 seconds to remove some cheek cells.
Spit saline/saliva solution back into dixie cup
Get your test tube and put 5ml of dish soap solution into your tube.
Then pour your saline solution over the soap solution.
Gently rock your soap/saline/salive solution for 2 minutes to mix it all together.
DO NOT shake it as this will break the DNA up and you won't be able to see it.
After rocking your solutin of 2 minutes get 10ml of rubbing alcoholand pour it in the test tube.
The 10ml of rubbing alcohol will sit on top of the other soapy solution but if you look at the division line between the two you will see hazy cloudy white strands coming up into the clear solution. That is your DNA. Yippee!
