exon

noun
- any segment of a discontinuous gene the segments of which are separated by introns Compare intron
exon
/ ĕ′ŏ /
- A segment of a gene that contains information used in coding for protein synthesis. Genetic information within genes is discontinuous, split among the exons that encode for messenger RNA and absent from the DNA sequences in between, which are called introns . Genetic splicing, catalyzed by enzymes, results in the final version of messenger RNA, which contains only genetic information from the exons.
- Compare intron
exon
- Stretches of DNA in genes that code for proteins . In eukaryotes , exons in a given gene are generally separated from each other by stretches of DNA that do not contain instructions for constructing proteins. ( Compare intron .)

Example Sentences
The researchers found COL11A1 and the other targets by comprehensively analyzing the subparts of genes called exons.
The active splicing factor splices out the inhibitory exon in the transcription factor, which turns on the genes that produce collagen.
Further, the genomes of vertebrate animals evolved to feature alternative splicing, in which a single gene can code for more than one protein by leaving out or adding exon sequences.
Those characteristics include the same number of exons, which encode the protein, and phases of introns, which act as interrupters to stop or start splicing of the RNA molecules transcribed from the gene.
Before being turned into proteins, genes are transcribed into introns, or strands of RNA that do not code for proteins, and exons that code for proteins.
