Abstract: The specific heat spectra of long-range correlated DNA molecules is theoretically analyzed for a stacked array of single-stranded DNA made up from the nucleotides guanine G, adenine A, cytosine C and thymine T arranged in the Fibonacci and Rudin–Shapiro quasiperiodic sequences, with the aim to compare them with those related with a genomic DNA sequence. The energy spectra are calculated using the one-dimensional Schrödinger equation in a tight-binding approximation with the on-site energy exhibiting long-range disorder and nonrandom hopping amplitudes.
