Organisms with alternative genetic codes resolve unassigned codons via mistranslation and ribosomal rescue

open access: yeseLife, 2018
Organisms possessing genetic codes with unassigned codons raise the question of how cellular machinery resolves such codons and how this could impact horizontal gene transfer.

Caenorhabditis nomenclature [PDF]

open access: yes, 2018
Genetic nomenclature allows the genetic features of an organism to be structured and described in a uniform and systematicway. Genetic features, including genes, variations (both natural and induced), and gene products, are assigned descriptorsthat ...

On the origin of degeneracy in the genetic code

open access: yesInterface Focus, 2019
The degeneracy of amino acid coding is one of the most crucial and enigmatic aspects of the genetic code. Different theories about the origin of the genetic code have been developed. However, to date, there is no comprehensive hypothesis on the mechanism

Genetic code on the dyadic plane

open access: yes, 2007
We introduce the simple parametrization for the space of codons (triples of nucleotides) by 8\times 8 table. This table (which we call the dyadic plane) possesses the natural 2-adic ultrametric.

Origins and Early Evolution of the tRNA Molecule

open access: yesLife, 2015
Modern transfer RNAs (tRNAs) are composed of ~76 nucleotides and play an important role as “adaptor” molecules that mediate the translation of information from messenger RNAs (mRNAs). Many studies suggest that the contemporary full-length tRNA was formed

Understanding the Genetic Code

open access: yesJournal of Bacteriology, 2019
The universal triple-nucleotide genetic code is often viewed as a given, randomly selected through evolution. However, as summarized in this article, many observations and deductions within structural and thermodynamic frameworks help to explain the ...

A p-Adic Model of DNA Sequence and Genetic Code

open access: yes, 2006
Using basic properties of p-adic numbers, we consider a simple new approach to describe main aspects of DNA sequence and genetic code. Central role in our investigation plays an ultrametric p-adic information space which basic elements are nucleotides ...

Stops making sense: translational trade-offs and stop codon reassignment [PDF]

open access: yes, 2011
Background Efficient gene expression involves a trade-off between (i) premature termination of protein synthesis; and (ii) readthrough, where the ribosome fails to dissociate at the terminal stop. Sense codons that are similar in sequence to stop codons

A simple model for the evolution of molecular codes driven by the interplay of accuracy, diversity and cost

open access: yes, 2008
Molecular codes translate information written in one type of molecules into another molecular language. We introduce a simple model that treats molecular codes as noisy information channels.
