Today we extracted DNA from wheat germ. We did this by putting ground up wheat germ into hot water and adding detergent to dissolve the plasma and nuclear membranes. We then decanted ethanol on top of the test tube containing the wheat germ, etc. The DNA precipitated up into the ethanol where we extracted it with a wooden stick.
The picture above shows the DNA (whitish cloudy fluid) floating in the ethanol (clear fluid) above the water containing the detergent and wheat germ (yellowish fluid)
