Each step in the extraction procedure aids in isolating DNA from other cellular materials. Explain why each step was necessary and put the DNA extraction procedure into context by drawing pictures and writing your responses.
In this lab, students will extract DNA from a strawberry using everyday materials and observe its physical appearance. As a result of participating in this activity, students will: Know how to extract DNA from strawberries. Observe what DNA looks like to the naked eye. Learn that DNA is found in every living and once living thing.
In this procedure, you will complete three steps with three key ingredients to isolate DNA. The first step is to dissolve the cell and nuclear membranes using detergent or soap; the second step is to break apart any cellular.
We will use an extraction buffer containing salt to break up protein chains that bind around the nucleic acids and dish soap to dissolve the lipid (fat) part of the strawberry cell wall and nuclear membrane. This extraction buffer will help provide us access to the DNA inside the cells. 1. What do you think the DNA will look like? 2.

• Complete a strawberry DNA extraction and explain why strawberries are effective for this experiment • Gain insight into molecular biology techniques, while gaining hands-on experience with DNA
Strawberries are a favorite specimen for DNA extraction because they are octoploid, which means they have eight sets of chromosomes. The procedure for extracting DNA from a strawberry is simple, and the results are usually obvious, it is easy to see the white strands of DNA within the pink solution of strawberry juice.
