The lack of pyrimidine diversity in meteorites remains a mystery since prebiotic chemical models and laboratory experiments have predicted that these compounds can also be produced from chemical precursors found in meteorites. Here we report the detection of nucleobases in three carbonaceous meteorites using state-of-the-art analytical techniques optimized for small-scale quantification of nucleobases down to the range of parts per trillion (ppt). In addition to previously detected purine…

Carbonaceous meteorites contain a wide range of extraterrestrial nucleobases
The results demonstrate that the purines detected in meteorites are consistent with products of ammonium cyanide chemistry, which provides a plausible mechanism for their synthesis in the asteroid parent bodies, and strongly supports an extraterrestrial origin.
Uracil in carbonaceous meteorites
Previous analyses of carbonaceous chondrites have demonstrated the presence of the biologically significant purines adenine, guanine, hypoxanthine and xanthine1–3. To date, however, no pyrimidine of
Meteorite-catalyzed syntheses of nucleosides and of other prebiotic compounds from formamide under proton irradiation
In the presence of meteorites and with high-energy protons, the production of unprecedented panels of nucleobases, sugars, and, most notably, nucleosides is observed and the detection of HCN oligomers suggests the occurrence of mechanisms based on the generation of radical cyanide species (CN·) for the synthesis ofucleobases.
Nucleobase synthesis in interstellar ices
The present results strongly suggest that the evolution from molecular clouds to stars and planets provides a suitable environment for nucleobase synthesis in space.
A new route for the prebiotic synthesis of nucleobases and hydantoins in water/ice solutions involving the photochemistry of acetylene.
A new explanation for the origin of hydantoins, purines, and pyrimidines in eutectic water/ice/urea solutions driven by ultraviolet irradiation of acetylene under anoxic conditions is reported.
Molecular Evolution of N-Containing Cyclic Compounds in the Parent Body of the Murchison Meteorite
Primitive meteorites contain various classes of organic compounds. Because the molecular distribution in these meteorites is not fully clarified, we do not yet understand the comprehensive formation
Understanding prebiotic chemistry through the analysis of extraterrestrial amino acids and nucleobases in meteorites.
This tutorial review focuses on meteoritic amino acids and nucleobases, exploring modern analytical methods and possible formation mechanisms, and discusses the unique window that meteorites provide into the chemistry that preceded life on Earth.
Extraterrestrial hexamethylenetetramine in meteorites—a precursor of prebiotic chemistry in the inner solar system
The first detection of hexamethylenetetramine and functionalized HMT species in the carbonaceous chondrites Murchison, Murray, and Tagish Lake is reported.
Extraterrestrial ribose and other sugars in primitive meteorites
The detection of extraterrestrial sugar in meteorites establishes the existence of natural geological routes to make and preserve them as well as raising the possibility that extraterrestrial sugars contributed to forming functional biopolymers like RNA on the early Earth or other primitive worlds.
