We address the question of whether such correlations may be a trivial consequence of the known mosaic structure (‘‘patchiness’’) of DNA. We analyze two classes of controls consisting of patchy nucleotide sequences generated by different algorithms—one without and one with long-range power-law correlations. Although both types of sequences are highly heterogeneous, they are quantitatively distinguishable by new fluctuation analysis method that differentiates local patchiness from long-range correlations. Application of this analysis to selected DNA sequences demonstrates that patchiness is not sufficient to account for long-range correlation properties.","url_abs":"https://journals.aps.org/pre/abstract/10.1103/PhysRevE.49.1685","url_pdf":"https://journals.aps.org/pre/pdf/10.1103/PhysRevE.49.1685","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"mosaic-organization-of-dna-nucleotides","repo_url":"https://github.com/Digiratory/StatTools","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"time-series","task_name":"Time Series Analysis"}],"methods":[{"method_slug":"dfa-random-walk","method_name":"DFA (Random Walk)"}],"datasets_introduced":[],"methods_introduced":[{"slug":"dfa-random-walk","name":"DFA (Random Walk)","full_name":"Detrended fluctuation analysis"}],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
