What is a Gene?

A BioBIKE Tour

One purpose of this investigative tour is to provide you with the opportunity to discover through computational experiment the physical nature of genes. Another, perhaps higher, purpose is to help you see that you have the ability to discover truth on your own, without the need to rely on the dubious authority of a textbook.
