Prebiotic evolution: Selecting for homochirality before RNA
نویسنده
چکیده
Recent results show that the self-assembly of long homochiral oligomers of a nucleotide analogue can be achieved by ligation of short oligomers of chirally mixed composition. Do these results show how the RNA world might have arisen?

On the origin of single chirality of amino acids and sugars in biogenesis.
The process of delineating the origins of the chemistry of life starts with the consideration of the molecules that might have existed on prebiotic earth and extends to the discussion of potential mechanisms for assembly of these molecules into informational polymers capable of self-replication and transmittance of genetic information. At some point along this pathway, the property of single ch...
متن کاملSynergetic mechanisms of chiral symmetry breaking in prebiotic evolution.
It was shown on the Frank autocatalytic reaction-diffusion scheme that strong environmental fluctuations, conditioned by external noise (e.g. sunlight fluctuation) and external macroscopic flows (e.g. ebb and flow), typical for conditions on prebiotic earth, may have been beneficial for chiral symmetry breaking and formation and stabilization of biomolecular homochirality.
متن کاملThe start of the Abiogenesis: Preservation of homochirality in proteins as a necessary and sufficient condition for the establishment of the metabolism
Biosystems contain an almost infinite amount of vital important details, which together ensure their life. There are, however, some common structures and reactions in the systems: the homochirality of carbohydrates and proteins, the metabolism and the genetics. The Abiogenesis, or the origin of life, is probably not a result of a series of single events, but rather the result of a gradual proce...
متن کاملMolecular Asymmetry in Prebiotic Chemistry: An Account from Meteorites
Carbonaceous Chondrite (CC) meteorites are fragments of asteroids, solar planetesimals that never became large enough to separate matter by their density, like terrestrial planets. CC contains various amounts of organic carbon and carry a record of chemical evolution as it came to be in the Solar System, at the time the Earth was formed and before the origins of life. We review this record as i...
متن کاملAbiotic synthesis of amino acids and self-crystallization under prebiotic conditions
Building on previous research on the origin and homochirality of life, this study focuses on analyses profiling important building blocks of life: the natural amino acids. The spark discharge variation of the iconic Miller experiment was performed with a reducing gas mixture of ammonia, methane, water and hydrogen. Amino acid analysis using liquid chromatography coupled with tandem mass spectro...
