@Sklivvz, of course I read the article. I was addressing this part by inorganic "In the lab, an identical suite of nucleobases and nucleobase analogs were generated in non-biological chemical reactions containing hydrogen cyanide, ammonia, and water. This provides a plausible mechanism for their synthesis in the asteroid parent bodies, and supports the notion that they are extraterrestrial," maybe I should use "non-bilogical" instead; I didn't think this will matter this much. @Beofett, FYI.
