Editing Coding region (section)

== Definition ==
Although this term is also sometimes used interchangeably with [[exon]], it is not the exact same thing: the [[exon]] can be composed of the coding region as well as the 3' and 5' [[untranslated region]]s of the RNA, and so therefore, an exon would be partially made up of coding region. The 3' and 5' [[untranslated region]]s of the RNA, which do not code for protein, are termed [[Non-coding region|non-coding]] regions and are not discussed on this page.<ref>{{Cite book|last=Parnell|first=Laurence D.|chapter=Advances in Technologies and Study Design|date=2012-01-01|chapter-url=http://www.sciencedirect.com/science/article/pii/B9780123983978000022|journal=Progress in Molecular Biology and Translational Science|volume=108|pages=17–50|editor-last=Bouchard|editor-first=C.|publisher=Academic Press|access-date=2019-11-07|editor2-last=Ordovas|editor2-first=J.

There is often confusion between coding regions and [[exome]]s and there is a clear distinction between these terms. While the [[exome]] refers to all exons within a genome, the coding region refers to sections of the DNA (or [[primary transcript]]) or a singular section of processed mRNA which specifically codes for a certain kind of protein. &nbsp;
