... samples from the National Park. They then ran a PCR with an rbcL primer pair to target the rubisco gene in plant chloroplasts. The PCR product was sequenced by a private company, Genewiz, and the DNA sequence was analyzed through DNA Subway. Twelve student groups, one or two students per group, isolated...

... red and white onions bought from a local grocery store. A lack of red coloration in white onions is a result of one or more mutations in the color production pathway. This mutation can be seen by the use of polymerase chain reaction (PCR) followed by gel electrophoresis. An absence of an amplified PCR...
