DNA are three letters full of paradox. What they represent remains little understood by the public, yet they are on everyone's tongue.
Amid the chatter of popular culture, the truth gets lost that DNA is one of the most powerful clues we have of the existence of a spiritual reality, maybe to the existence of God.
An acronym for deoxyribonucleic acid, DNA refers to the form taken by the biological information that directs the production of proteins and other cell components. In 1953, James Watson and Francis Crick famously described its double-helix shape. The information thus encoded, the genome, influences how a living organism's body gets constructed, though how far this goes, and how it works, are questions that remain obscure.
We talk about DNA as familiarly as we do the USA. The idea that your genes determine your susceptibility to diseases and addictions is a stock theme of popular health discussions. On TV cop shows, law-enforcement officials are constantly using DNA to solve cases, whether new or "cold" - as real police do.
For a fee, DNA testing can shed light on anyone's genetic ancestry, including whether you have "Jewish genes." There is supposed to be a "God gene" for religious belief in general. And a "gay gene." And so on.
But all this is trivial compared to the largely unheralded insight gained from the Human Genome Project, completed in 2003. The insight is disturbing. It is that while DNA codes for the cell's building blocks, the information needed to build the rest of the creature is seemingly, in large measure, absent.
Consider the Hox "master" genes that supposedly determine the spatial configuration of the front and back ends of creatures as diverse as frogs, mice and humans. As British physician James Le Fanu writes in a fascinating new book, Why Us? How Science Rediscovered the Mystery of Ourselves (Pantheon), Swiss biologist Walter Gehring showed that "the same 'master' genes mastermind the three-dimensional structures of all living things...
The same master genes that cause a fly to have the form of a fly cause a mouse to have the form of a mouse." The physically encoded information to form that mouse, as opposed to that fly, isn't there. Instead, "It is as if the 'idea' of the fly (or any other organism) must somehow permeate the genome that gives rise to it."
