Related to intervening sequence: lariat


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.]


(Genetics) biochem a stretch of DNA that interrupts a gene and does not contribute to the specification of a protein. Compare exon2
[C20: from intr(agenic) (regi)on]
