Biology The Structure of DNA
DNA's double helix structure was discovered in 1953 by Watson, Crick, and Franklin. Each human cell contains about 6 feet of DNA packed into a nucleus smaller than a speck of dust. If all your DNA were uncoiled and laid end to end, it would stretch from Earth to the Sun and back about 600 times.
