Pre-Engineering students extract DNA from a strawberry
Caddo Kiowa Technology Center Pre-Engineering students extract DNA to test foods for the presence or absence of Genetically Modified Organisms. The first step in this process is to learn about DNA in general and to extract it from a food.
“Strawberries contain a lot of DNA, relatively speaking, so they are the food of choice for extracting DNA for beginners,” explains Instructor Marcia Harmon.
After the students extracted the DNA, they wanted to look at the cellular debris and strands of DNA under a microscope, taking the lesson a step further than what was required of them.
Next, the students will test corn that is genetically modified and oats that aren’t in addition to other foods that the students choose to test for the presence of genetic modification.
This lesson is part of the PLTW Pre-Engineering Environmental Sustainability course.
