Food Fish Identification From Dna Extraction Through Sequence Analysis, Heather E. Hallen-Adams Jan 2015

Food Fish Identification From Dna Extraction Through Sequence Analysis, Heather E. Hallen-Adams

Faculty Publications in Food Science and Technology

This experiment exposed third and fourth year undergraduates and graduate students taking a course in advanced food analysis to DNA extraction, polymerase chain reaction (PCR), and DNA sequence analysis. Students provided their own fish sample, purchased from local grocery stores, and the class as a whole extracted DNA, which was then subjected to PCR, gel electrophoresis and Sanger sequencing. Students retrieved their sequences and identified their fish using the NCBI BLAST nucleotide database. Slightly more than half of the samples yielded sequences identical or close to expected (based on the identification of the fish on the packaging); some other samples ...

Students who participate in active and experiential learning activities develop a better understanding of basic scientific principles and are also more likely to be retained in a STEM discipline. Developing such activities, however, can be difficult. In the present study, we sought to develop classroom activities to engage university students and increase understanding of the theory and practice of forensic science. One common accessory amongst the target audience was the ever-present media, both social and popular (entertainment). In fact, a majority of students report watching at least one of the many popular forensic science shows on TV. Therefore, we hypothesized ...
