Daniel Gibson says that being able to synthesize new genomes may "dramatically speed up the process of engineering microbes that can carry out tasks such as efficiently producing biofuels or vaccines," as he tells MIT's Technology Review. Last year, Gibson's team at the J. Craig Venter Institute announced that they made a synthetic genome using yeast cells to assemble the oligonucleotides, and Gibson has now developed a way of doing that without the yeast.
