DNA LAB!

In class we built our own DNA.  First we mixed a gram of wheat germ with 25 milliliters of warm water.  Wheat germ is a little brown substance that is soft.  Then we mixed the two substances together for about three minutes. After the substance was mixed it turned a brown color, then we had one fourth of teaspoon of detergent. After the detergent was in the test tube we mixed it for about five minutes.  After we mixed the detergent with the substance we added 14 milliliters of alcohol to the test tube.  Make sure when you pour the alcohol in the test tube you tilt the test tube and pour the alcohol solution in slowly so the that they don't mix.  So it looks like that there is a light brown yellow substance in the bottom of the test tube and a clear substance on the top of the test tube.  Now this gets really interesting.  But make sure that you don't mix after you pour the alcohol. As you wait and stare at the test tube for a couple minutes a clear filmy substance starts to form.  It is really weird how it starts to form it comes form the bottom and starts moving up.  While you keep watching in like ten minutes more and more of this starts to float up to the top.  It was funny because Cody started screaming when the substance started floating up.  The clear substance is DNA.  I am not really sure how it was formed but it was DNA.  As a group we grabbed a stick and poked at the DNA.  As you grabbed it with the stick more and more DNA would come up.  We made our own DNA! In this lab I truly learned how to make our own DNA.  This lab was very interesting and fun because I made something that I never thought I could or would make.

This is how our test tube looked like. The clear white substance floating to the top is DNA created and being created.  It doesn't look to interesting but once you see it forming its really cool and interesting.
