Life has been evolving on earth for about 3.7 billion years.
In spite of its diversity, all living things have one thing in common � DNA,
a fundamental code containing just four chemical letters; adenine, thymine, guanine, and cytosine. Until now.
Synthetic biologists from the Scripps Research Institute in California have, for the first time, created semi-synthetic E. coli bacteria with a 6-letter genetic code.
That might sound like something out of Jurassic Park, but even in Jurassic Park the cloned dinosaurs were coded using A, T, G and C.
These new semi-synthetic organisms are an entirely new variation on life.
The two synthetic bases that have been added are dNaM and dTPT3, but for short they�re called X and Y.
