in·tron  (ntrn)

A segment of a gene situated between exons that is removed before translation of messenger RNA and does not function in coding for protein synthesis.
[intr(agenic), occurring within a gene (intra- + genic) + -on.]
intron  (ntrn)
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.
