Not if you believe in panspermia.
- vadimberman 9y agoIt depends on the kind of panspermia. If it's about generic organic molecules then the DNA is a local construct. If it's about microorganisms, then it's different.
- seiferteric 9y agoTrue. It's also possible that DNA is the only form of life that really works, but we just don't know yet.
- lovemenot 9y agoThere's 6-base pair organisms now. https://www.sciencealert.com/new-organisms-have-been-formed-using-the-first-ever-6-letter-genetic-code https://www.sciencealert.com/new-organisms-have-been-formed-... Also, RNA seems to work and it's possible we started out using RNA and later evolved to DNA.
