intron
(ĭn’trŏn)
A segment of a gene situated between exons that does not function in coding for protein synthesis. After transcription of a gene to messenger RNA, the transcriptions of introns are removed, and the exons are spliced together by enzymes before translation and assembly of amino acids into proteins. Compare exon.
A stretch of DNA in a gene that does not code for proteins. In eukaryotes, introns in a given gene separate stretches of DNA that contain instructions for constructing proteins. (Compare exon.)
