Strawberry DNA Extraction Lab | Subject Labs

Описание: 🍓 Join ‪@TrySubject‬ in the lab as we embark on an amazing journey to extract and actually see DNA from strawberries—no microscope needed! This fascinating experiment is perfect for science enthusiasts of all ages and requires only a few common household items. Get ready to be amazed as you watch DNA clump before your eyes! 🧬

🔬 Materials Needed:

Strawberries (5-6 will do)
Ziploc bag
Deionized water
Dishwashing liquid (clear)
Salt
Coffee filter
Cup
Pineapple juice
Isopropyl alcohol (chilled)
Stirring rod or a spoon
👩‍🔬 Steps to Follow:

Step 1: Prep the DNA Buffer Solution: Mix half a cup of deionized water with a squirt of dishwashing liquid and a pinch of salt.

Step 2: Strawberry Mashing: Place 5-6 strawberries in a Ziploc bag and mash thoroughly to break down the cell walls.

Step 3: Mix with Buffer Solution: Add the buffer solution to the mashed strawberries in the bag and mix well.

Step 4: Filtering: Use a coffee filter to strain the strawberry mixture into a cup.

Step 5: Enzyme Reaction: Add a few drops of pineapple juice to the filtered solution to help break down proteins and release the DNA.

Step 6: DNA Precipitation: Slowly add chilled isopropyl alcohol to create a layer that will help DNA precipitate and become visible.

Step 7: Extraction: After a few minutes, use a stirring rod or spoon to extract the clumped DNA.
