Scripps researchers have designed a bacterium with two unnatural bases, called X and Y, which could someday help them produce new molecules for medical therapies
Scientists have taken an important step towards the possibility of creating synthetic life with the development of a form of artificial evolution in a simple chemistry set without DNA.
For more than half a century scientists have looked on the DNA molecule as life's blueprint. Now biological engineers are beginning to see the molecule not as a static plan, but more like a snippet of life's computer code that they can program.
