In genetics, exons are the regions of a transcribedgene that are not spliced out and which are retained in the final mRNA molecule as part of the protein-coding region. See also intron, the sections of RNA that are spliced out.
Exon trapping[?] is a clever molecular biology technique that exploits the existence of the intron-exon architecture to find new genes.
