Testing for Genetically Modified Foods Using PCR
Taylor, Ann; Sajan, Samin
Journal of Chemical Education, v82 n4 p597-598 Apr 2005
The polymerase chain reaction (PCR) is a Nobel Prize-winning technique that amplifies a specific segment of DNA and is commonly used to test for the presence of genetic modifications. Students use PCR to test corn meal and corn-muffin mixes for the presence of a promoter commonly used in genetically modified foods, the cauliflower mosaic virus 35S promoter.
