# Symmetries by base substitutions in the genetic code predict 2' or 3' aminoacylation of tRNAs

## TL;DR

This paper uncovers symmetrical patterns in the genetic code through base substitutions, revealing how these symmetries predict the aminoacylation specificity of tRNAs at the 2' or 3' position.

## Contribution

It introduces a novel framework of two-fold symmetries in the genetic code that links base substitutions to tRNA aminoacylation specificity.

## Key findings

- Identifies complete sets of symmetries in the genetic code
- Shows how base substitutions exchange properties of degeneracy and aminoacylation
- Predicts tRNA aminoacylation sites based on symmetry patterns

## Abstract

This letter reports complete sets of two-fold symmetries between partitions of the universal genetic code. By substituting bases at each position of the codons according to a fixed rule, it happens that properties of the degeneracy pattern or of tRNA aminoacylation specificity are exchanged.
