Understanding DNA and Its Role

The video explains that DNA, a molecule found in nearly every cell of the body, contains the genetic code that defines who we are. DNA is made up of nucleotides represented by the letters A, C, G, and T. The sequence of these letters determines our physical traits and family history, much like how the order of letters in a book determines its story. The Genographic Project aims to decode DNA from many people to learn more about human origins and history.
