The process of synthesis
by which azoic elements have reached their present multiplicity and complexity is an evolution, the same process entirely as the
biologist traces in the order of living things, and the
synthetic chemical compound embodies in itself a complex relativity capable of being expressed in most exact laws, which reflect the evolutionary emergence of its substance as much as do the organs of an animal explained in terms of evolutionary development.
Peng Yin, a systems
biologist at Harvard University, who was not involved in the new research, says he is impressed
by the work and calls it «an important advance for molecular programming, dynamic DNA nanotechnology and in vitro
synthetic biology.»
Graduate student Emily Thomas,
synthetic biologist Jonathan Silberg and their colleagues built upon established techniques that attach bio-orthogonal (noninterfering), artificial amino acids to transfer RNA (tRNA), which are used
by ribosomes to synthesize proteins.
By fitting DNA into an engineering template, the messy field of biology emerges as a complex but somewhat predictable system — one that
synthetic biologists have begun to maneuver in recent years.
Zoloth is especially intrigued
by the kinds of internal moral choices
synthetic biologists must make.
A team of
synthetic biologists led
by Farren Isaacs at Yale University has now rewritten these rules.
It also offers an alternative to the approach used
by biologist Craig Venter of building a genome from scratch to impart new properties to cells — laborious because even the smallest error kills the cell (see «Craig Venter: Why I put my name in
synthetic genomes «-RRB-.
Yuste, for example, says that keeping human benefits in mind is important, but he wonders whether the project's original sharp focus on tool development may be diluted if the NIH advisory panel is dominated
by traditional neuroscientists, rather than a more interdisciplinary mix of scientists including nanoscientists, optogeneticists, and
synthetic biologists.
Obama called for the study in May after a team led
by biologist J. Craig Venter reported that it had inserted a
synthetic genome into a self - replicating cell.
That concern is one reason the research team, led
by Christina Smolke, a
synthetic biologist at Stanford University in Palo Alto, California, stopped short of making a yeast strain with the complete morphine pathway; medicinal drug makers also primarily use thebaine to make new compounds.
Because
synthetic biologists can get the same amino acid from multiple codons, they can avoid troublesome DNA repeats
by swapping in different codons that achieve the same effect.
By transferring the gene for melanopsin into human embryonic kidney cells,
synthetic biologist Martin Fussenegger of the Swiss Federal Institute of Technology in Zurich and colleagues made these cells light - sensitive as well.
This was the question asked at a symposium organized
by the Wildlife Conservation Society at Cambridge University this week, attended
by about 80
synthetic biologists and conservationists.
