Barry Commoner on DNA



Unraveling the Secret of Life

by Barry Commoner

The title of James Watson’s new book, DNA: The Secret of Life, echoes the boast voiced on the day, fifty years ago, when he and Francis Crick discovered the structure of this now-famous molecule. The inexplicable uniqueness of life has for centuries been mystery enough to elicit religious doctrine, let alone scientific research. Therefore it is fitting that, to celebrate the fiftieth anniversary of the double helix, Time’s February 17, 2003 cover depicts an updated Adam and Eve standing before the biblical tree of life, each entwined in the coils of a golden helix anatomically placed to symbolize their recent loss of innocence. In the story itself, “Solving the Mysteries of DNA”, Time tells us the long-sought secret that Watson and Crick’s scientific discovery revealed: “The beauty of DNA is that its form is its function. It’s a self-reproducing molecule that carries the instructions for making living things from one generation to the next.” An accompanying molecular diagram explains exactly “How DNA Works” by making “a copy of itself.”

All this is to say that the living cell is not merely a sack of chemicals, but a unique network of interacting components, dynamic yet sufficiently stable to survive. The living cell is made fit to survive by evolution; the marvelously intricate behavior of the nucleoprotein site of DNA synthesis is as much a product of natural selection as the bee and the buttercup. In moving DNA from one species to another, biotechnology has broken into the harmony that evolution produces, within and among species, over many millions of years of experimentation. Genetic modification is a process of very unnatural selection, a way to perversely reinvent the inharmonious arrangements that evolution has long ago discarded. The biotechnology industry has stood Darwin on his head.

It is a truism that in our society, such a new industry is created not for the purpose of enhancing scientific understanding, but inthe hope of a competitive financial return. Unfortunately, the science on which biotechnology is founded has become, to a large extent, distorted by this process as well, and is itself in need of critical revision. If the science is to be redirected, and the unpredictable, uncontrolled experiment that is biotechnology is to be sent back to the laboratory where it rightly belongs, we will need to accept this task as our own and set Darwin back on his feet.
