This document describes an experiment to detect the presence of genetically modified organisms (GMOs) in various food items using polymerase chain reaction (PCR) and gel electrophoresis. Samples tested included papaya, soy milk, wheat, and corn. DNA was extracted from the samples and amplified using PCR with green and red master mixes targeting the CaMV35S and NOS promoters and terminators. The results of gel electrophoresis were inconclusive due to possible errors in pipetting, DNA concentration, primer amount, evaporation, and contamination. The experimenters plan to repeat the process to improve results and apply it to identify GMOs in Puerto Rican products and their effects on the local diet.
