Specific, kind'a. There are many different combinations of chemical compositions in bacteria, virus, and so on. And what elements or chemicals exist in our bodies that are not natural? All of them are.
Maybe, but it's not totally accurate.
Matter doesn't self-replicate, not even in cells. At least not in the sense of elementary particles. They are just what they are. Produced by stars and such.
What's replicating is molecules and systems of molecules. And crystals replicate too, and lipids, and in a sense stars too... So, the distinction between life and non-life, animate and inanimate, and so on is ultimately without a clear distinction. There's no clear-cut line between the two.
The thing is, it's the system of matter that replicates. The composition, and it replicates through physics, chemistry, and natural properties innate in the matter. The bits in a computer with transistors become Windows, Linux, or OS X. The transistors are inanimate, while Windows quite seems to have its own opinions at times.
Basically, the animate always consist of the inanimate. The inanimate becomes animate through symbiosis and synergy. Life is emergent from the matter.
Sorry, I'm keeping on adding to this post
It's like cars can become traffic, which becomes rush hour, which becomes "I'm late to work!" A car isn't traffic, but many cars on a freeway is.
