What is the Strawberry DNA Extraction Lab?
The strawberry DNA extraction lab is an experiment that involves extracting DNA from strawberries. The procedure involves mashing up strawberries, adding a mixture of salt and detergent to the mashed strawberries, and then filtering the mixture to isolate the DNA. This lab is a popular experiment in high school biology classes and is often used to teach students about DNA and genetics.
What materials are needed for the Strawberry DNA Extraction Lab?
The materials needed for the strawberry DNA extraction lab include:
- Fresh strawberries
- Ziploc bag
- Detergent
- Salt
- Measuring cups and spoons
- Funnel
- Coffee filter or cheesecloth
- Isopropyl alcohol
- Pipette or dropper
How do you conduct the Strawberry DNA Extraction Lab?
To conduct the strawberry DNA extraction lab, follow these steps:
- Mash up 1-2 strawberries in a Ziploc bag.
- Add 1/4 teaspoon of salt and 1 tablespoon of detergent to the mashed strawberries.
- Gently mix the contents of the bag for 2-3 minutes, being careful not to create too many air bubbles.
- Place a funnel over a container and a coffee filter or cheesecloth over the funnel.
- Pour the strawberry mixture through the filter, collecting the liquid in the container.
- Add a layer of isopropyl alcohol to the container, pouring it slowly down the side of the container so that it forms a separate layer on top of the strawberry mixture.
- Wait for a few minutes and observe the white, stringy DNA that forms in the alcohol layer.
- Use a pipette or dropper to collect the DNA and transfer it to a separate container for observation.
