It's just DNA with non-standard base pairs. Boring for a molecular biologist (like me). Non-standard genetic codes always get wiped out by natural selection, they just hinder lateral gene transfer too much. And we go the last 4 billion years of evolution as evidence for that. It will neither saves us from nothing, nor is it any threat to us.

Apart from the brainless hyperbole in your link, which is a good example of the sort of idiocy that threatens us. Complete ignorance of actual understanding of real nature -and how it works- is evident on your link.

Sorry for bringing reality into this Dave's thread of nonsense.
