The hypothesis is that the DNA can be separated from the other cell components.

You will gather materials, chop onions into small pieces, measure out ingredients, line a funnel with a coffee filter, pour the mixture into the funnel, let the liquid filter through, add a meat tenderizer solution, add ice-cold ethanol, swirl gently, and observe the results.

You will need 200mL of distilled water, 2 onions, 1 pair of glasses, 2 bottles of ethanol, 10mL of dishwashing detergent, 1.5gm of table salt, 5mL of EDTA, 3gm of meat tenderizer, 1 cutting board, 1 kitchen knife, 3 coffee filters, 1 large funnel, 1 thermometer, 300mL of water at 60 degrees C, 100mL of ice, 2 beakers (250mL or bigger), 1 wooden spoon, 1 small test tube, 1 plastic transfer pipet, and 15mL of ice-cold ethanol.

The results of the experiment showed that DNA could live separated from the other cell components. This stands out as an interesting observation, as it shows that DNA can survive on its own.

This science project is interesting and unique because it shows that a lot of DNA can be taken out of the onion and we can see the DNA at the end, even though we cannot see it when it's inside the onion cell.

Experiment variations to consider include using strawberries instead of onion to extract DNA.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
