Abstract
DNA is often described as the "language of life" because it encodes biological information using nucleotide sequences. Unlike the traditional view focused on codon-to-amino acid mapping in coding regions, the vast non-coding genome reveals complex organizational patterns resembling natural language. This paper outlines essential approaches in DNA linguistics, including formal language theory, RNA secondary structure modeling, statistical methods, and phylogenetic analysis. Additionally, recent research on Indo-European populations shows correlations between lexical and phonemic traits and asymmetrical patterns of genetic inheritance. Together, these perspectives deepen our understanding of genome regulation, evolution, and the striking parallels between genetic and linguistic systems.
