The document summarizes a student project applying DNA barcoding to identify various organisms. The students were able to use DNA barcoding to correctly identify known samples like a dandelion and ant. They also used it to identify unknown tree species on their campus and an insect provided by a professor. Additionally, they tested the technique on sushi from local restaurants to check for mislabeling, finding some discrepancies between DNA results and listed species. In conclusion, the students demonstrated that DNA barcoding can accurately identify both known and unknown biological samples.
