This matters because circRNAs can exist as different full-length isoforms, and their back-splice junction (BSJ) connects the two ends of the RNA. Treating a circular RNA like a linear transcript can therefore overlook sequence information near this junction.","pubDate":"Thu, 22 Oct 2026 20:20:01 EDT","url":"https://phys.org/news/2026-10-ai-tool-microrna-sites-circular.html"},"indexado":"2026-10-23T00:28:21.218Z"}}
