DNA Extraction from Wheat Germ

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ. Extracting DNA from raw wheat germ may sound difficult, but this experiment can be performed with materials found in your local grocery or hardware stores. This is a simplified version of the same technique routinely used by research scientists to isolate DNA.
