Carbonaceous chondrites are a class of meteorite known for having a high content of water and organics. In this study, abundances of the nucleobases, i.e., the building blocks of RNA and DNA, found in carbonaceous chondrites are collated from a variety of published data and compared across various meteorite classes. An extensive review of abiotic chemical reactions producing nucleobases is then performed. These reactions are then reduced to a list of 15 individual reaction pathways that could…

Meteorites and the RNA World: A Thermodynamic Model of Nucleobase Synthesis within Planetesimals.
It is found that cytosine is unlikely to persist within meteorite parent bodies due to aqueous deamination and Fischer-Tropsch (FT) synthesis is found to be the dominant source of nucleobases within the model planetesimal, non-catalytic (NC) synthesis may still be significant under certain chemical conditions.
Possible Ribose Synthesis in Carbonaceous Planetesimals
The origin of life might be sparked by the polymerization of the first RNA molecules in Darwinian ponds during wet-dry cycles. The key life-building block ribose was found in carbonaceous chondrites.
The Photochemistry of Purine in Ice Analogs Relevant to Dense Interstellar Clouds
The photochemistry of purine in more complex ices of astrophysical interest is examined and the results are compared with those from simpler ice mixtures and the effects of competing parallel synthesis of organic compounds in the ices are examined.
Origin of the RNA world: The fate of nucleobases in warm little ponds
It is found that RNA polymers must have emerged very quickly after the deposition of meteorites (less than a few years), and their constituent nucleobases were primarily meteoritic in origin and not from interplanetary dust particles.
Prebiotic Precursors of the Primordial RNA World in Space: Detection of NH2OH
One of the proposed scenarios for the origin of life is the primordial RNA world, which considers that RNA molecules were likely responsible for the storage of genetic information and the catalysis
Prebiotic Chemistry and Chemical Evolution of Nucleic Acids
Over the last 65 years, many potentially prebiotic synthetic mechanisms have been experimentally demonstrated for nucleobases, and their presence in extraterrestrial materials has been extensively verified, suggesting some of these are valid explanations for how the environment produces them.
Constraining the Time Interval for the Origin of Life on Earth.
The lack of consensus on whether there was a late heavy meteorite bombardment that was significant enough to prevent life is the largest uncertainty in estimating the time of the habitability boundary, and the biosignature boundary is more closely constrained.
A Consistent Reduced Network for HCN Chemistry in Early Earth and Titan Atmospheres: Quantum Calculations of Reaction Rate Coefficients.
CVT using energies computed with density functional theory as a feasible and accurate method for calculating a large network of rate coefficients of small-molecule reactions is presented.
Mineral-Organic Interactions in Prebiotic Synthesis
A common criticism of “prebiotic chemistry research” is that it is done with starting materials that are too pure, in experiments that are too directed, to get results that are too scripted, under


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.
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites
Carbonaceous meteorites as a source of sugar-related organic compounds for the early Earth
It is reported that a variety of polyols are present in, and indigenous to, the Murchison and Murray meteorites in amounts comparable to amino acids, and analyses of water extracts indicate that extraterrestrial processes including photolysis and formaldehyde chemistry could account for the observed compounds.
A voyage from dark clouds to the early Earth
Stellar nucleosynthesis of heavy elements, followed by their subsequent release into the interstellar medium, enables the formation of stable carbon compounds in both gas and solid phases.
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.

Structural and stable isotopic characteristics suggest that a number of environments may have contributed to the organic inventory, including interstellar space, the solar nebula and the asteroidal meteorite parent body.
