<conspiracyFile>Desktop genetic engineering.
|
|
By Kevin Kelly
|
|
I spent a day recently a biotechnology trade show, snooping around the
|
|
aisles of plumbing and lob gear to see how close we ore to having gene
|
|
equipment that would work in a suburban garage. was looking for
|
|
off-the-shelf components that could be assembled by a dedicated individual
|
|
into o lob for homebrewed DNA. / was surprised by how close it has come.
|
|
While most of the equipment for biotechnology is either delicate but
|
|
cumbersome laboratory research instruments, or massive industrial/chemical
|
|
plumbing for production purposes, there are o couple of items that hove
|
|
miniaturized the research methods into o suggestive desktop space. The
|
|
leader in self-contained DNA coding gear is Applied Biosystems. Their star
|
|
contraption is a table-top box linked to a Macintosh computer that will
|
|
assemble a short string of DNA from the order that you type into the Mac.
|
|
The unit generates the DNA sequence from the some four amino acids that
|
|
cellular DNA does. in this case the amino acids are provided in small
|
|
bottles in the front of the box, along with bottles of solvent to drive the
|
|
process. The DNA is outputted" into a tiny capillary tube. While the
|
|
machine is 99.8% accurate in what it constructs, the major (and it is major)
|
|
drawback is that it con assemble sequences that are no more than 180 units
|
|
long, which would make one short gene, at most. (Genes, like words, vary in
|
|
length.) Since human genes come in the order of about one billion units,
|
|
there is a way to go in improvements. On the other hand, since the
|
|
alteration of even one gene con make a big difference in a living organism
|
|
(many congenital diseases are due to a single gene), there is still power in
|
|
being able to rewrite o couple of hundred units. A complementary box made by
|
|
Applied Biosystems works in reverse. Rather than going from code to DNA, it
|
|
goes from DNA to code. It takes a bit of existing DNA and reads" its
|
|
sequence out as a display on the computer - ATTCGGACA, etc., for instance.
|
|
Not only con this verify a sequence one builds, but its main purpose is to
|
|
unravel the genetic code encrypted in all living things. It too is severely
|
|
limited in the amount of DNA it con handle at one time. But the task of
|
|
deciphering chromosomes that are 5000000 genes long would be o bummer
|
|
without it. The two machines work as a pair. Both together would fit onto a
|
|
kitchen countertop. These units by themselves are not enough to do
|
|
biotechnology research. Sundry other hi-tech items, as well as low-tech ones
|
|
like incubators, cold rooms and basic labware, are essential. But these two
|
|
systems ore the heart of the hard work; they automate what was tedious and
|
|
unpredictable toil just a few years ago. I'd guess that true basement
|
|
biotechnology is still at least a decade away, if only because of the price
|
|
$50000 for each of these machines alone)aond the expertise Ph.0) needed to
|
|
get them going. -Kevin Kelly Information from: Applied Biosystems, inc.,
