Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites

open access: yesNature Communications, 2022
All DNA/RNA nucleobases were identified in carbonaceous meteorites. Having been provided to the early Earth as a component in carbonaceous meteorites, these molecules might have played a role for the emergence of genetic functions in early life.
