A binary representation of the genetic code

Area of Science:

• Bioinformatics
• Molecular Biology
• Genetics

Background:

• The canonical genetic code translates nucleotide sequences into amino acid sequences.
• Understanding the relationships between genetic code structure and amino acid properties is crucial for molecular biology.
• Existing representations do not fully capture the nuances of nucleotide structure and amino acid physicochemical properties.

Purpose of the Study:

• To introduce a novel binary representation of the genetic code.
• To correlate this binary representation with nucleotide structure and amino acid physicochemical properties.
• To analyze the impact of mutations and estimate their functional consequences.

Main Methods:

• Assigning unique 2-bit identifiers to each of the four mRNA bases.
• Indexing 64 triplet codons with 6-bit labels.
• Utilizing principal component analysis (PCA) to correlate bit positions with amino acid properties.

Main Results:

• The binary representation reflects the hierarchical organization of DNA replication/repair and translation systems.
• Mutations (transition and transversion) are naturally expressed as binary operations.
• Physicochemical properties of amino acids correlate with specific bit positions in their labels.

Conclusions:

• The developed binary system provides a new framework for analyzing the genetic code.
• It enables the analysis of mutation severities and the estimation of their impact on protein functionality.
• This approach offers insights into the conservativeness of point mutations and their potential effects on protein function.
