Scientists Create First Living Organism With 'Artificial' DNA: "The alien E. coli contains just a single pair of foreign DNA bases out of millions. But Benner sees no reason why a fully alien cell isn’t possible. “I don’t think there’s any limit,” he says. “If you go back and rerun evolution for four billion years, you could come up with a different genetic system.”
But creating a wholly synthetic organism would be a huge challenge. “A lot of times people will say you’ll make an organism completely out of your unnatural DNA,” says Romesberg. “That’s just not going to happen, because there are too many things that recognize DNA. It’s too integrated into every facet of a cell’s life.”"
