- Journey into DNA
"Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into chromosomes, and how do chromosomes relate to the human body?
This exploration allows you to travel to the tiny world of DNA. Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell."
