American biologist Craig Venter has announced that he has created the
first ever "artificial life form" on Earth at the J. Craig Venter
Institute, a U.S. laboratory and research center.
The breakthrough is the culmination of fifteen years of research and
builds upon earlier work, research which saw the creation of a synthetic
bacterial genome and the transplant of a genome from one species of
bacteria into a second. "Synthia", a nickname derived from ''synthetic
lifeform'', combines these two techniques to create a "new lifeform".
A genome was created using synthetic chromosomes made from bottles of
chemicals, the chromosomes sequenced to create a genome using as a
template an existing bacterium . A bacterium from different species then
had its own genome removed and the synthetic one transplanted in its
place. Venter's achievement is that the new genome switched on and the
new cell replicated to create new cells. A process likened to the
booting of a computer with a new operating system.
Venter's achievement has been dismissed by some as falling short of a
true technolgical breakthrough, claiming that rather than creating a new
genome, that he has merely recreated the genome of an existing
bacterium: "a technical tour de force" but not breakthrough science,
according to Caltech geneticist David Baltimore.
Amongst the possibilities of artificial bacteria talked about are
bacteria tailored to solve climate change by taking CO2 out
of the atmosphere and to develop new vaccines. More complex organisms
could include algae which would both be a source of biofuels and a
CO2 remover. This is not, however, the instant solution to
the Earth's major problems. Although enough is now known to duplicate a
genome, there is insufficient knowledge as to what the role of
individual chromosomes within the genome do. Any advances in synthetic
biology to design life forms would require a much greater understanding
of how the creation of proteins are coded in a genomes chromosomes.
