New proteins from artificially modified genes.

Expanding DNA's alphabet lets cells produce novel proteins

One of the first lessons in high school biology: All life is made up of four DNA building blocks known by the letters A, T, C and G. Paired together, they form DNA's ladder-like rungs. Now there's a new rung on that ladder.

A team at The Scripps Research Institute in La Jolla, California, expanded the genetic alphabet, creating two artificial DNA "letters" called X and Y. A few years ago, the researchers brewed up a type of E. coli bacteria commonly used for lab research that contained both natural DNA and this new artificial base pair — storing extra genetic information inside cells.

This is another one that bothers me a little - just hoping that the bio-secutity employed is pretty good.

Bit more detail on "Inside science" on BBC, first 7min are zbout the strong Stone Age women, then this mstter.
