Gelling…

AP Biology students John Bendernagel, Christopher Vuong, and Evan Tizzard load DNA samples into gels as part of Mrs. Tassin’s class activity. Kyle Happel, M.D. ’89 has been teaching this activity for Jesuit students since 2011. AP Biology students used the PCR procedure (polymerase chain reaction) to amplify copies of DNA samples from four different suspects plus a sample taken from a crime scene. The students were shown the micropippetting technique. The samples of DNA were then separated with gel electrophoresis, and then each gel was examined under UV lighting. The illuminated DNA fragments were compared to the crime scene fragments. Thanks again for the visit, Dr. Happel!
