Qué (quién) es Exon - definición

ANY PART OF A GENE THAT WILL ENCODE A PART OF THE FINAL MATURE RNA PRODUCED BY THAT GENE, AFTER INTRONS HAVE BEEN REMOVED BY RNA SPLICING
Exonization; Exons; Expressed region; Expressed regions; MRNA exon; Exonic
  • Exons in a messenger RNA precursor (pre-mRNA). Exons can include both sequences that code for amino acids (red) and untranslated sequences (grey). Introns — those parts of the pre-mRNA that are not in the mRNA — (blue) are removed, and the exons are joined (spliced) to form the final functional mRNA. The 5′ and 3′ ends of the mRNA are marked to differentiate the two untranslated regions (grey).
  • Introns are removed and exons joined in the process of RNA splicing. RNAs could be [[mRNA]] or [[non-coding RNA]]

C18: representing the pronunciation of Fr. exempt 'free from' (because they were exempt from normal duties).
Exon         
An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term exon refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts.

Wikipedia

Exon

An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term exon refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts. In RNA splicing, introns are removed and exons are covalently joined to one another as part of generating the mature RNA. Just as the entire set of genes for a species constitutes the genome, the entire set of exons constitutes the exome.
