That's really interesting. The article and.somethibg else (I forget now) made me presume it was naturally occurring. If it's largely biological how did it get to be part of RNA? Maybe a different molecule started it off?

Interesting those experiments on early dNA did not replicate. Undergrade was a long time ago so last I had heard it was probably all the rage. Of course, ever will we debate what conditions are the right conditions, etc.

Thanks for the informative post.
