On a somber morning Watson and Crick entered the Eagle Pub located near the Cavendish Laboratory of Cambridge University. However, Watson was not the doctor from books by Conan Doyle. “We have solved the mystery of life,” the younger of them shouted in excitement despite the embarrassment of his senior companion. The latter put on a modest air for no good reason, as the DNA structure model suggested by the co-authors would be recognized by the scientific community and crowned with the Nobel Prize. It is easy to see the famous double helix. One just has to visit the Center of Molecular Genetics under the University of Chicago. They have a staircase of this very shape there.
