CHS students learn to extract DNA in biology class 2016-02-07 - Campbellsville High School, 230 W Main, Campbellsville, KY - Photo Calen McKinney, Campbellsville Independent Schools photo. Campbellsville High School students recently learned how to extract DNA from strawberries. In Jessica Bradshaw's biology classes, students are studying DNA and learning where it's found, what it's made of and what it does. To see what DNA looks like, students performed an experiment. First, students smashed strawberries inside a plastic bag. They then added a mixture of water, shampoo and salt. Students poured their strawberry mixture onto a coffee filter, to drip into a cup. Then, students poured chilled alcohol onto the mixture to get the strawberry's DNA to separate. In this photo CHS biology teacher Jessica Bradshaw, third from left, talks to students, from left, sophomores Brookelyn Franklin, Makala Antle and Lauren Riddle about how chilled alcohol separates DNA from the liquid mixture.
