EVALUATING THE INTERACTIONS BETWEEN AMINOACYL-tRNA SYNTHETASES AND ELONGATION FACTOR TU IN PROTEIN SYNTHESIS
Our data raise several evolutionary questions, and the first is about the aminoacyl-tRNA synthetases themselves.
The aminoacyl-tRNA synthetases help establish the rules of the genetic code, by mediating the translation of DNA to protein.
A novel proposed alignment of the aminoacyl-tRNA synthetases was found using this system.
Therefore, an RNA-only-based protein synthesis system would require a set of RNA molecules capable of synthesizing aminoacyl-RNAs, which are produced by the protein aminoacyl-tRNA synthetases in extant biology.
