| exon shuffling | <molecular biology> Process by which the evolution of proteins with multifunctional domains could be accelerated. If exons each encoded individual functional domains, then introns would allow their recombination to form new functional proteins with minimal risk of damage to the sequences encoding the functional parts. (18 Nov 1997) |

| exon | <molecular biology> The sequences of the primary RNA transcript (or the DNA that encodes them) that exit the nucleus as part of a messenger RNA molecule. In the primary transcript neighbouring exons are separated by introns. (18 Nov 1997) |

| exon shuffle | The variation in the patterns by which RNA may produce diverse sets of exons from a single gene. (05 Mar 2000) |
| exon trapping | <molecular biology, technique> A technique used to identify exons with a specialised vector. The vector has two exons that are normal, splicedtogether in a transcript.Fragments of DNA can be inserted into the intron, and when the insert is an exon, the exon is splicedinto the transcript, thereby giving a longer transcript that can be detected by Northern blotanalysis.
