exon


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

ex·on

(ek'son),
A portion of DNA that codes for a section of the mature messenger RNA obtained from that DNA, and is therefore expressed ("translated" into protein) at the ribosome.
[ex- + on]

exon

/ex·on/ (ek´son) the coding region in a gene.

exon

(ĕk′sŏn)
n.
A nucleotide sequence that is found in a gene, codes information for protein synthesis, and is transcribed to messenger RNA.

ex·on′ic adj.

exon

[ek′son]
Etymology: Gk, exo + genein, to produce
the part of a DNA molecule that contains the code for the final messenger RNA. Compare intron.

exon

The segment of deoxyribonucleic acid (DNA) in a gene that codes for some part of the messenger ribonucleic acid (RNA). Any segment that is represented in the RNA product. Segments that do not code for RNA are called introns.

exon

or

extron

(‘ex'for expressed) or - the DNA segments of an INTERRUPTED split gene that are transcribed into RNA and then into the gene product. Exons occur along the length of the gene, and are separated by segments called INTRONS whose sequences are also transcribed into RNA. The intron RNA segments are then excised, leaving behind the exon RNA segments that join up to form a functional RNA molecule, a process called RNA SPLICING.

exon

regions of a primary RNA transcript in eukaryotic cells that are coding and are joined together when introns are spliced-out, to make the functional mRNA.
