SECIS element in viruses?

In reference to the following selection, under the heading 'Species distribution'

"The SECIS element is found in a wide variety of eukaryotes, prokaryotes and viruses". Four citations are listed; however, none of them studied viruses. If no citations support the claim for viruses, it should be removed.

The phrase may more accurately read:

"SECIS elements are found in Archaea, Eubacteria, and Eukaryota". ++++++ I know of at least one human virus which uses SECIS and I have a PhD in virology, someone should look hard before deleting. —Preceding unsigned comment added by 165.230.19.144 (talk) 18:30, 25 February 2010 (UTC)[reply]

A reference for this claim is the review article(C)The Royal Society of Chemistry: Birringer, M., Pilawa, S., Flohe, L., 2002. Trends in selenium biochemistry. Nat. Prod. Rep. 19: 693-718. DOI: 10.1039/b205802m

Letters in the picture

What do the letters in the picture mean? Shouldn't the only letters be the standard RNA bases A, C, G and U? Icek (talk) 14:54, 2 January 2010 (UTC)[reply]

They are IUPAC redundancy codes. The colours give an indication of sequence conservation. There probably should be a caption reflecting this.--Paul (talk) 16:11, 2 January 2010 (UTC)[reply]
