Crystal Basis Model: Codon-Anticodon Interaction and Genetic Code Evolution

TL;DR

This paper uses a crystal basis model to identify minimal anticodon sets for mitochondrial translation and explores the evolution of the genetic code through codon-anticodon interactions, aligning well with observed data and accepted evolutionary schemes.

Contribution

It introduces a minimum principle within the crystal basis model to determine anticodon sets and analyzes genetic code evolution from ancient to early stages.

Findings

Identifies 22 anticodons for mitochondrial translation matching observed data.

Analyzes genetic code evolution consistent with accepted schemes.

Provides a theoretical framework linking codon-anticodon interactions to code evolution.

Abstract

Imposing a minimum principle in the framework of the so called crystal basis model of the genetic code, we determine the structure of the minimum set of 22 anticodons which allows the translational-transcription for animal mitochondrial code. The results are in very good agreement with the observed anticodons. Then, we analyze the evolution of the genetic code, with 20 amino acids encoded from the beginning, from the viewpoint of codon-anticodon interaction. Following the same spirit as above, we determine the structure of the anticodons in the Ancient, Archetypal and Early Genetic codes. Most of our results agree with the generally accepted scheme.
