==Common misuse of the term==

Common incorrect uses of the term ''exon'' are that 'exons code for protein', or 'exons code for amino-acids' or 'exons are translated'. However, these sorts of definitions only cover [[Protein coding gene|protein-coding genes]], and omit those exons that become part of a [[non-coding RNA]]<ref>{{cite journal |last1=Khan |first1=MR |last2=Wellinger |first2=RJ |last3=Laurent |first3=B |title=Exploring the Alternative Splicing of Long Noncoding RNAs. |journal=Trends in Genetics |date=August 2021 |volume=37 |issue=8 |pages=695–698 |doi=10.1016/j.tig.2021.03.010 |pmid=33892960|s2cid=233382870 }}</ref> or the [[untranslated region]] of an [[mRNA]].<ref>{{cite journal |last1=Lu |first1=J |last2=Williams |first2=JA |last3=Luke |first3=J |last4=Zhang |first4=F |last5=Chu |first5=K |last6=Kay |first6=MA |title=A 5' Noncoding Exon Containing Engineered Intron Enhances Transgene Expression from Recombinant AAV Vectors in vivo. |journal=Human Gene Therapy |date=January 2017 |volume=28 |issue=1 |pages=125–134 |doi=10.1089/hum.2016.140 |pmid=27903072|pmc=5278795 }}</ref><ref>{{cite journal |last1=Chung |first1=BY |last2=Simons |first2=C |last3=Firth |first3=AE |last4=Brown |first4=CM |last5=Hellens |first5=RP |title=Effect of 5'UTR introns on gene expression in Arabidopsis thaliana. |journal=BMC Genomics |date=19 May 2006 |volume=7 |pages=120 |doi=10.1186/1471-2164-7-120 |pmid=16712733|pmc=1482700 |doi-access=free }}</ref> Such incorrect definitions still occur in overall reputable secondary sources.<ref>{{Cite web |title=Exon |url=https://www.genome.gov/genetics-glossary/Exon |archive-url=https://web.archive.org/web/20230316084632/https://www.genome.gov/genetics-glossary/Exon |archive-date=2023-03-16 |access-date=2023-03-23 |website=Genome.gov |language=en}}</ref><ref>{{Cite web |title=Exon |url=https://www.nature.com/scitable/definition/exon-exons-270/ |archive-url=https://web.archive.org/web/20230323060403/https://www.nature.com/scitable/definition/exon-exons-270/ |archive-date=2023-03-23 |access-date=2023-03-23 |website=www.nature.com |publisher=Scitable |language=en}}</ref>
