intronIntron (ger.)

  • A segment of an RNA molecule which is excised during or soon after its transcription from DNA and takes no part in forming the eventual gene; a segment of a DNA molecule which codes for this. (OED 2011)
    gene exon
    1978

    The notion of the cistron […] must be replaced by that of a transcription unit containing regions which will be lost from the mature messenger—which I suggest we call introns (for intragenic regions)—alternating with regions which will be expressed— exons.
