In this new organism, the researchers added two new bases, X and Y, creating a new form of DNA that (as far as we know) has never occurred after billions of years of evolution on Earth or elsewhere in the universe. Remarkably, the semi-synthetic alien organism continued to reproduce normally, preserving the new alien DNA during reproduction. In the future, this breakthrough should allow for the creation of highly customized organisms — bacteria, animals, humans — that behave in weird and wonderful ways that mundane four-base DNA would never allow.
