Or When Science Oversteps Its Bounds
Or More stories destined to serve as the basis of a Will Smith movie
Summary: This post is my reaction to the news that scientists have built a man-made genome.
Wired offered a breathless report today: Scientists Build First Man-Made Genome; Synthetic Life Comes Next. The New York Times ran the story with the headline: Scientists Take New Step Towards Man-Made Life.
Both publications were talking about a recent scientific achievement: the manufacture of a bacterium genome by sticking together a bunch of smaller gene sequences. This is a big deal because it’s by far the largest genome ever created by man. The Wired story quotes one of the scientists:
“The J. Craig Venter Institute will be able to take a file stored on a computer and using synthetic chemistry, turn that information into life,” said Chris Voigt, a University of California at San Francisco synthetic biologist. “I would be shocked if it doesn’t come out in six months. I think they’ve done it.”
“…Once this becomes routine, it allows us to build whatever genome we want,” Voigt said. “You can design a genome to incorporate a particular chemical process to change what the cells are eating and what the cells are making. You can make robotic cells.”
Am I the only one who suspects that there may be infinite potential ramifications of ‘creating life’ in this fashion, as yet unconsidered by the good folks at the J. Craig Venter Institute?
The New York Times piece has the grace to mention some of the challenges ahead:
In any case, there are many hurdles to overcome before Dr. Venter’s vision of “life by design” is realized. The synthetic genome made by Dr. Venter’s team was not designed from scratch, but rather was a copy, with only a few changes, of the genetic sequence of a tiny natural bacterium called Mycoplasma genitalium.
Moreover, Dr. Venter’s team, led by a Nobel laureate, Hamilton Smith, has so far failed to accomplish the next —and biggest — step. That would be to insert the synthetic chromosome into a living microbe and have it “boot up” and take control of the organism’s functioning.
Interesting phrase, that: “take control of the organism’s functioning.” In The Biology of Belief, the book I mentioned yesterday, Bruce Lipton, Ph.D. argues that the nucleus (where the genome lives) couldn’t possibly be considered the ‘brain’ of a cell:
Following enucleation [removal of the nucleus], many cells can survive for up to two or more months without genes. Viable enucleated cells do not lie about like brain-dead lumps of cytoplasm on life-support systems. These cells actively ingest and metabolize food, maintain coordinated operation of their physiologic systems (respiration, digestion, excretion, motility, etc.), retain an ability to communicate with other cells, and are able to engage in appropriate responses to growth and protection-requiring environmental stimuli.
Unsurprisingly, enucleation is not without side effects. Without their genes, cells are not able to divide, nor are they able to reproduce any protein parts they lose through the normal wear and tear of the cytoplasm. The inability to replace defective cytoplasmic proteins contributes to mechanical dysfunctions that ultimately result in the death of the cell.
…If the nucleus and its genes are not the cell’s brain, then what exactly is the DNA’s contribution to cellular life? Enucleated cells die, not because they have lost their brain but because they have lost their reproductive capabilities. Without the ability to reproduce their parts, enucleated cells cannot replace failed protein building blocks, nor replicate themselves. So the nucleus is not the brain of the cell—the nucleus is the cell’s gonad!
If the genes are not the brain, but rather the reproductive organs, what are the implications for creatures ‘designed’ with man-made reproductive systems?
Consider this other excerpt from Lipton’s book:
…biological dysfunctions can result from miscommunication anywhere within these complex pathways. When you change the parameters of a protein at one point in such a complex pathway, you inevitably alter the parameters of other proteins at innumerable points within the entangled networks… Notice that proteins within one functional group, such as those concerned with sex determination…, also influence proteins with a completely different function, like RNA synthesis (i.e., RNA helicase). “Newtonian” research scientists have not fully appreciated the extensive interconnectivity among the cell’s biological information networks.

In my PMP training, we learned a formula to calculate communication pathways: N(N-1). If you’ve got five stakeholders you have to communicate with for a project, and they can all communicate with each other as well, then the total number of pathways is 30: five stakeholders plus you equals six (N), times 5 (N-1).
If all the proteins in the body are connected to all other proteins, and there are roughly 100,000 proteins in the body (according to Lipton), then the number of pathways is, oh, somewhere around ten billion.
I’m no geneticist, and I’m aware that my calculation is incredibly simplistic. But my question is valid: do you think that the simultaneous and interconnected interactions among all these proteins are fully understood by the people creating synthetic life?
What is your reaction to this story? Does it scare you? Does it excite you? Should these scientists be given medals and extra funding, or forced to shut up shop?
