Papillion La Vista Community Schools students in the Biomedical pathway recently conducted hands-on laboratory work studying DNA to better understand the relationship between genotype (genetic makeup) and phenotype (physical characteristics).

During the innovative lab session, students had the unique opportunity to analyze their own DNA to determine if they possessed a specific genetic trait related to taste perception. The experiment focused on identifying whether students had the genetic markers to be a "supertaster" or "non-taster" of certain bitter chemicals.

The laboratory procedure involved students carefully "digesting" or cutting up DNA samples to view them in a gel medium. This process allowed students to visualize their genetic material and make direct connections between their genes and observable traits.

This real-world application of genetic science demonstrated to students how small variations in DNA sequences can lead to significant differences in physical characteristics. While the lab focused on a relatively simple trait like taste perception, it opened discussions about how similar genetic variations can influence more complex traits and medical conditions, such as cystic fibrosis.

The hands-on nature of the experiment particularly resonated with students, who found excitement in examining their own DNA and using scientific methods to predict their physical traits. This type of experiential learning helps bring complex genetic concepts into practical focus for students in the Biomedical pathway.

The laboratory experience represents one of many ways PLCS is working to provide students with engaging, real-world applications of scientific concepts, preparing them for potential futures in medical and scientific fields.
