Abstract: Parts of DNA sequences known as exons and introns play very different roles in coding and storage of genetic information. Here, the authors show that their conducting properties are also very different. Taking into account long-range correlations among four basic nucleotides that form double-stranded DNA sequence, the authors calculate electron localization length for exon and intron regions. Analyzing different DNA molecules, the authors obtain that the exons have narrow bands of extended states, unlike the introns where all the states are well localized. The band of extended states is due to a specific form of the binary correlation function of the sequence of basic DNA nucleotides.
