The nucleus of each of your cells contains multiple long strands of DNA with all the instructions to make your entire body. If you stretched out the DNA found in one of your cells it would be 2 to 3 meters long. To fit all of this DNA inside a tiny cell nucleus the DNA is wrapped tightly around proteins. The enzyme in meat tenderizer is a protease, which is an enzyme that cuts proteins into small pieces. As this enzyme cuts up the proteins the DNA will unwind and separate from the proteins. The protease in meat tenderizer actually comes from plants, but animals also make protease
Detergent
Add a small amount of detergent to a test tube (about 0.25 mL). Put a glove on the hand you will use to hold your test tube not the hand you will use to pour. Now carefully pour the drink containing your cheek cells into the test tube with detergent until the tube is half full.
To get the DNA out of your cheek cells you need to break open both the cell membranes and the nuclear membranes. Cell membranes and nuclear membranes consist primarily of lipids Dish washing detergent like all soaps, breaks up lipids. This is why you use detergents to remove fats from dirty dishes. Adding the detergent to you cheek cell solution will break open the cell membranes and nuclear membranes and release your DNA into the solution

Sample of Cells
Obtain a cup with sports drink. You will need to get thousands of your cheek cells in the sports drink in order to extract enough DNA to see. Therefore you should swish the sports drink around in your mouth vigorously for at least one minute. Then spit the drink back into the cup
DNA Extracting from Cells
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.
How do you think your body replaces the cells that come off the lining of your mouth when you eat To extract DNA from your cells you will need to separate the DNA from the other types of biological molecules in your cells.
What are the other main types of large biological molecules in cells You will be using the same basic steps that biologists use when they extract. You will follow these 3 easy steps to extract the DNA
