Extracting dna from wheat germ results
Try notto create foam.Use an eyedropper remove any foam from the top of the solution.Tilt the test tube, beaker or jar at an angle. Do not mix the two layers together. DNApreThis lab was very easy and straight forward. But most importantly it might have been the very extracting dna from wheat germ results lab Autumn and I have managed to do correctly.To start of the lab we placed one gram of raw wheat germ into a test tube and then added 20 ml of warm tap water. We then stirred the mixture together for quite some time, (about 3-5 minutes) as we did this we observed that the mixture turned a yellowish color.
Next we added a few drops of Dawn dish washing detergent to the mixture and stirred the new mixture once every minute for five minutes. (the mixture become slightly bluer) After that step we titled the test tube at a little less than a 40 degree angle and very carefully poured 14 ml of alcohol down its side. As we did this the alcohol formed a separate layer on top of the mixture of soap, water, and wheat germ. Finally we let the test tube sit and rest for around eleven minutes. So, our class did a DNA extraction of a wheat germ. The warm water will also denature enzymes that may damage the DNA.
