Examples
-
Using aminoacyl-RNAs instead of direct amino acid affinity, a single optimized molecular translation protocol can evolve for all amino acid side chains
-
Since aminoacyl-tRNA synthetases are proteins, that necessity suffers from the chicken-and-egg problem when trying to explain the origin of translation.
-
Aminoacyl-tRNA synthetases (aaRSs) are responsible for creating the pool of correctly charged aminoacyl-tRNAs that are necessary for the translation of genetic information (mRNA) by the ribosome.

-
There is already chemical necessity between amino acids and their codons due to the aminoacyl-tRNA synthetases.
-
Our framework fits naturally the recently proposed picture that early evolution was dominated by HGT, as evidenced by detailed phylogenetic (15), biochemical (16), and structural (17) analyses of the aminoacyl-tRNA synthetases.

There is already chemical necessity between amino acids and their codons due to the aminoacyl-tRNA synthetases.
-
There is already chemical necessity between amino acids and their codons due to the aminoacyl-tRNA synthetases.
-
We present a phylogenetic analysis to determine whether a given tRNA molecule was established in evolution before its cognate aminoacyl-tRNA synthetase.
-
In addition if binding affinity is a gauge then the binding affinity of the active sites of aminoacyl tRNA synthetases is instructive.
