We identify "life" with the capability of self-replication plus some other features. In other conditions, for instance on other planets, it could be possible for self-replication to happen in a way different from the RNA/DNA-based one.
I remember stumbling, years ago, on research and papers that studied this kind of possibility. But I'm having a hard time finding the old references or new ones.
Do you have interesting papers and research material to share about this? Thank you!
Got one! XNA. Here's an article example (boo behind a paywall).
It's available for free on a popular "scientific research paper file sharing site"[^1] if you search for its title.
