Comparing and contrasting onion and cheek cells. Inquiry Question. How do you think an onion cell would be different from a cheek cell? . Describe shape, size, and organelle differences that you expect to observe.. Extracting DNA from Your Cells . Today you will extract DNA from your cheek cells. This process is similar to what is done when any DNA-containing tissue is found at a crime scene. . Cells from the lining of your mouth come loose easily, so you will be able to collect cells containing your DNA by swishing a liquid around in your mouth. The cells from the lining of your mouth also come off whenever you chew food. . Do Now: Check answers to homework using answer key on star board.
