Abstract

The origin of guanine has been unknown, thoughthere are some reports concerning its abiotic synthesis. Weshow here that guanine, as well as uracil and cytosine, aresynthesized from a 90%N2–10%CO–H2O gas mixture via a complex organic product produced with the high-temperature and rapidquenching technique. This result implies that a large amountof complex organic matter including precursors of bioorganiccompounds might have been produced on the primitive earthafter cometary impacts.
