Quizplus · Accepted Answer

Pulsed-field gel electrophoresis (PFGE) is a genetic method that uses restriction enzymes to cut genomic DNA into fragments, which are then separated based on size by gel electrophoresis. The resulting banding pattern can be used to compare isolates and determine their relatedness, making it a valuable tool in epidemiological investigations of food-borne illness outbreaks.
