by Chris Carrington, The Daily Sheeple:
Since life began DNA has been composed of two base pairs, A-T and C-G. Every living organism on the planet has DNA that is made up from combinations of these base pairs…until now.
Scientists at the Scripps Research Institute have engineered a new code, a new base pair, and they have incorporated it into a single bacterium by supplying the building blocks in the form of a fluid applied externally to the bacterium it replicated, just as a natural organism would. The bacteria they chose for their experiments is E. coli.
The research was published in the online journal Nature.
Preempting the inevitable questions about a runaway reaction and the world being faced with an entirely new, semi-synthetic organism, the researchers were quick to point out that they have to supply nutrients externally to make the bacteria replicate. Nowhere in the literature can I find any indication that they have considered mutation, adaptation or anything else that could lead to this ‘enhanced’ E. coli making a break for freedom.
