An outron is a nucleotide sequence at the 5' end of the primary transcript of a gene that is removed by a special form of RNA splicing during maturation of the final RNA product. Whereas intron sequences are located inside the gene, outron sequences lie outside the gene.

An outron is a nucleotide sequence at the 5' end of the primary transcript of a gene that is removed by a special form of RNA splicing during maturation of the final RNA product. Whereas intron sequences are located inside the gene, outron sequences lie outside the gene.

== Characteristics == The outron is an intron-like sequence possessing similar characteristics such as the G+C content and a splice acceptor site that is the signal for trans-splicing. Such a trans-splice site is essentially defined as an acceptor (3') splice site without an upstream donor (5') splice site.
