The '''Exon''' is the region of a [[gene]] that contains the code for producing the gene's [[protein]]. Each exon codes for a specific portion of the complete protein. In some species (including humans), a gene's exons are separated by long regions of [[DNA]] (called [[introns]] or sometimes "[[junk DNA]]") that have no apparent function.
