Not if you believe in panspermia.

It 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.

True. It's also possible that DNA is the only form of life that really works, but we just don't know yet.

There's 6-base pair organisms now. 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.
