intron

in·tron (

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 [ˈɪntrɒn]

(Life Sciences & Allied Applications / Genetics) Biochem a stretch of DNA that interrupts a gene and does not contribute to the specification of a protein Compare exon²

[from intr(agenic) (regi)on]

intron (

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.
