(genetics) The proposed mixing of different exons either within a gene or between two nonallelic genes.

a molecular biology technique to identify potential exons in a fragment of eukaryote DNA of unknown intron-exon structure.

An exon junction complex is a protein complex which forms on a pre-messenger RNA strand at the junction of two exons which have been joined together during RNA splicing.

In molecular biology, exon skipping is a form of RNA splicing used to cause cells to “skip” over faulty or misaligned sections (exons) of genetic code, leading to a truncated but still functional protein despite the genetic mutation.
