Today was our DNA Lab. Students worked in pairs trying to extract DNA from human cheeks cells. It’s tricky. Cheek cells are large and it’s hard to get very many of them, so collecting a visible amount of DNA is a delicate task. The basic steps included getting a sample of cheek cells, breaking the cell membranes using soap, unraveling the DNA using meat tenderizer, using alcohol to isolate the DNA, and then observing (see video above). You can find a copy of the lab posted below. All in all, it was a challenging yet productive day.
