Abstract

We use q-exponential distributions, which maximize the nonextensive entropy S_q (defined as S_q ≡ (1 - ∑_i p_i^q) / (q - 1)), to study the size distributions of non-coding DNA (including introns and intergenic regions) in all human chromosomes. We show that the value of the exponent q describing the non-coding size distributions is similar for all chromosomes and varies between 2 ≤ q ≤ 2.3 with the exception of chromosomes X and Y.
