Linguistic mechanism of the evolution of amino acid frequencies and genomic GC content [PDF]

open access: yesarXiv, 2006
Much information is stored in amino acid composition of protein and base composition of DNA. We simulated the evolution of amino acid frequencies and genomic GC content by a linguistic model. It is showed that the evolution of genetic code determines the evolution of amino acid frequencies and genomic GC content.

Genetic Code Table: A note on the three splittings into amino acid classes [PDF]

open access: yesarXiv, 2009
This note represents the further progress in understanding the determination of the genetic code by Golden mean (Rakocevic, 1998). Three classes of amino acids that follow from this determination (the 7 "golden" amino acids, 7 of their complements, and 6 non-complements) are observed now together with two further possible splittings into 4 x 5 and 5 x ...

Indigenous amino acids in primitive CR meteorites [PDF]

open access: yesarXiv, 2008
CR meteorites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites, two of which show the highest amino acid concentrations ever found in a chondrite. EET92042, GRA95229 and GRO95577 were analyzed for their amino acid content using high performance liquid chromatography with ...
