Designing new genomes could speed the creation of vaccines and biofuel-producing bacteria
The bacteria growing on stacks of petri dishes in Daniel Gibson's lab are the first living creatures with a completely artificial genome. The microbes' entire collection of genes was edited on a computer and assembled by machines that create genetic fragments from chemicals and by helper cells that pieced those fragments together. Gibson hopes that being able to design and create entire genomes, instead of just short lengths of DNA, will dramatically speed up the process of engineering microbes that can carry out tasks such as efficiently producing biofuels or vaccines.
