Genome transplant changes one species into another

For the first time, scientists have completely transformed a species of bacteria into another species by transplanting its complete set of DNA. The achievement marks a significant step toward the construction of synthetic life, with applications including the production of clean fuel in as little as a decade. The researchers hope that genome transplantation will enable the production of synthetic microbes for green energy sources, pharmaceuticals, chemicals and textiles.

The scientists’ results show that it is possible to transplant the complete set of DNA—the genome—from one species into the genome of a different species, so that the recipient organism is phenotypically and genotypically identical to the donor organism.
