Delicious DNA

In 1953, Francis Crick and James Watson discovered the structure of the DNA molecule, the double helix. Their discovery led to many developments in the fields of forensic science and biotechnology and in the understanding of heredity and genetic diseases. The two high school seniors featured in this SciFri Vfideo were able to apply DNA extraction for a more practical application: to find out what really is in the food that we eat. In this activity, students will review and discuss the definition, function and importance of DNA.
