I have decided to make considerable improvement to this article. Expect significant revision and additions to this page by May 14th. This includes all suggested revisions and information regarding the specific components and mutation of operons.

There appears to be no way to italicise the lac in the link to lac operon. Anyone know how to do it? It comes out as ''lac'' operon. Also remember that in prokaryotic genetics, cistron/operon names are italicised and always start in lower case. The protein product always starts in upper case and is not italicised. So lac Z is the cistron and LacZ is the protein.-- Alun 05:48, 13 May 2005 (UTC)
What is positive gene regulation? What is negative gene regulation?
The OED online defines an operon as specific to prokaryotes. I recall that operons are specific to prokaryotes, though my memory is far from perfect. I am assuming the OED is correct. What is the general opinion.-- Alun 07:38, 13 May 2005 (UTC)
The OED is incorrect (out of date, really). Operons appear most broadly in bacteria and archaea, but also appear in some eukaryotes. Parakkum 19:41, 13 November 2006 (UTC)
I am confused by this definition, and im not sure its correct... What is meant by structural genes? Genes which produce structural proteins? - Zephyris Talk 12:29, 26 November 2006 (UTC)
I think this page needs a bit of reorganization. I'm not really qualified, but I may be next year. If it hasn't been done by then, I'll attempt it.
It would be better if the contents of the article were more hierarchical. I'll meditate some more on how exactly to accomplish that. -- aciel 22:27, 8 April 2007 (UTC)
I wish someone made a good image of attenuation (trp operon) . it would be so much easier to understand it. —Preceding unsigned comment added by 62.68.181.184 ( talk) 20:47, 16 June 2008 (UTC)
I'm revamping the article, trying to put some more beef on it, and to make it more user-friendly. I need some advice on a few points. First among them: the opening line to the article states that operons are encoded in found DNA. Since operons also occur in viruses, where the genomic material is RNA, what would you guys think of me changing DNA to "genomic material", as in "operones are a length of code in the genomic material of an organism"? Shiningheart ( talk) 13:19, 20 December 2009 (UTC)
I don't know if there are, but on the other hand, I don't know that there aren't! So, what do you think? Should we rather err on the side of inclusion, or stick to DNA? Shiningheart ( talk) 18:28, 20 December 2009 (UTC)
I've revamped the article, creating the "structure of an operon" category, and folding the "promoter" and "operator" subcategories into it. I'm thinking of folding the "operon as a transcriptional unit" category as well. I've also added some citations and references, so could someone let me know how to get the "this article lacks sufficient verification or citations" tag? Criticism will be happily accepted from all!

The article states that rRNA genes often exist in operons, and then it says that an operon is transcribed into single mRNA. This is not the only one article on Wikipedia where authors seem to think that there is no other RNA than mRNA, which results in absurd statements like the one I mentioned above. Guys, majority of transcription in cells produces ribosomal and not messenger RNA! Please, correct this asap. 62.121.66.29 ( talk) 11:18, 9 April 2011 (UTC)
