to do[edit]

there is a small wikipedia article on guide RNAs http://en.wikipedia.org/wiki/Guide_RNA . Content from that article could be folded into the present article. Dabs (talk) 15:03, 13 April 2011 (UTC)[reply]
re-organization of the content would be helpful. There are sections defined by mechanisms, then sections defined by taxonomy, and then other sections not defined by either. I think the best way to organize this would be by biochemistry, that is, distinguish gRNA-mediated insertional/deletional editing from base conversion, then distinction C-to-U editing (one type in plant organelles, other types in other cases), A-to-I editing, and any other conversion types that are known. Dabs (talk) 15:08, 13 April 2011 (UTC)[reply]
Some notes on the references (following reformatting) Dabs (talk) 15:03, 13 April 2011 (UTC)[reply]
- this article has undesirable clumping of references, e.g., about a dozen references for the simple statement that editing has been found in trypanosome mitochondria. Later in the section, most of the individual references are used for specific points. This is confusing for the reader and should be changed.
- it would be useful to add pubmed ids to the citations. It would take someone about 20 minutes to look up all the ids and add "| pmid=XXXXXXXX" to each citation ( add it just before the close of the double-curly-braces). This would allow the user to click through to explore further.
- there is little reason to cite multiple reviews that cover the same ground.
- the use of references is uneven. The section on A-to-I editing has none.
I'm pretty sure that this does not give an accurate picture of taxonomic distributions. C-to-U editing happens in plant mitos, plant chloroplasts, trypanosomes, animal nuclei. gRNA-mediated pan-editing is attributed to T. brucei but is found in related organisms.

poly-A section[edit]

I removed the poly-A section on the grounds that it is confusing to readers to have this distinct topic in the present article. Dabs (talk) 15:09, 13 April 2011 (UTC)[reply]

RNA processing redirect[edit]

Are we really sure that RNA editing is the same thing as RNA processing? In my mind, RNA processing refers more to polyadenylation, etc... Philbradley 19:52, 21 November 2006 (UTC)[reply]

Yeah, pretty sure that RNA editing = RNA editing. Recury 19:55, 21 November 2006 (UTC)[reply]

Whoops - I meant to question the RNA processing to RNA editing redirect. I've edited my above comment. Thoughts?Philbradley 14:33, 25 November 2006 (UTC)[reply]

yeah someone should change it if they can as i cant! it confused me as im studying biotechnology

(Note: RNA processing was redirected to Post-transcriptional modification in 2007 -R. S. Shaw (talk) 06:46, 16 April 2011 (UTC))[reply]

And is this the same thing as RNA interference? Andrew Davidson (talk) 13:07, 9 January 2012 (UTC)[reply]

Suggestions generated by an automatic JavaScript program[edit]

Consider adding more links to the article; per Wikipedia:Manual of Style (links) and Wikipedia:Build the web, create links to relevant articles.^[?]
If there is not a free use image in the top right corner of the article, please try to find and include one.^[?]
You may wish to consider adding an appropriate infobox for this article, if one exists relating to the topic of the article. ^[?] (Note that there might not be an applicable infobox; remember that these suggestions are not generated manually)
Per Wikipedia:Manual of Style (headings), headings generally should not repeat the title of the article. For example, if the article was Ferdinand Magellan, instead of using the heading ==Magellan's journey==, use ==Journey==.^[?]
There are a few occurrences of weasel words in this article- please observe WP:AWT. Certain phrases should specify exactly who supports, considers, believes, etc., such a view.
- it has been
- might be weasel words, and should be provided with proper citations (if they already do, or are not weasel terms, please ~~strike~~ this comment).^[?]
Watch for redundancies that make the article too wordy instead of being crisp and concise. (You may wish to try Tony1's redundancy exercises.)
- Vague terms of size often are unnecessary and redundant - “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, and “all”. For example, “~~All~~ pigs are pink, so we thought of ~~a number of~~ ways to turn them green.”
As done in WP:FOOTNOTE, footnotes usually are located right after a punctuation mark (as recommended by the CMS, but not mandatory), such that there is no space in between. For example, the sun is larger than the moon [2]. is usually written as the sun is larger than the moon.[2]^[?]
Please ensure that the article has gone through a thorough copyediting so that it exemplifies some of Wikipedia's best work. See also User:Tony1/How to satisfy Criterion 1a.^[?]

You may wish to browse through User:AndyZ/Suggestions for further ideas. -(t) Josve05a (c) 21:27, 16 June 2013 (UTC)[reply]

RNA Editing: General Article Critique[edit]

This critique is based on the outlines set forth in "Evaluating Wikipedia".

Introduction:

-For the layman, it may be helpful to have a schematic of the possible outcomes of RNA editing: start/stop codons created/eliminated, amino acid changes, etc.

RNA editing in plants and mitochondria:

Though certainly an important topic segment to include, this section is a bit under cited and misworded. The following edits and additions would help to strengthen the article. -There has been a considerable amount of research in mitochondrial and plastid RNA editing, separately. There is sufficient information available in the literature to warrant separate subheadings for plastid and mitochondrial editing. -"RNA-editing sites are found mainly in the coding regions of mRNA, introns, and other non-translated regions." Vague and confusing. The citation is over 25 years old. This can be expanded upon with up-to-date literature. -"The exact mechanism is unknown, but previous studies have speculated the involvement of gRNA and the editosome complex. The reason behind that specific idea arose from the fact that there are too many editing sites that needed to be changed in those organelles for a deaminase." In the plastid, the current model has PPR proteins as the conveyors of RNA editing site specificity, not gRNA. As a deaminase enzyme has eluded discovery, the PPR proteins are suspected to serve this function as well. -The second half of the section lacks citations.

RNA editing may be involved in RNA degradation

-This may not warrant its own section within the article. The information in this section is based on a single study with seemingly inconclusive findings with regards to RNA editing and RNA degradation.

In general, this article is well-cited. Most of the citations, however, are pre-2000. While this does not make them obsolete, there have been many studies in the last 15 years that have revealed insightful information on this topic. Including the information from some of these references would help to strengthen this article and bring it up-to-date.

Coleoid cephalopods?[edit]

Perhaps a section should be added for coleoid cephalopods? See:

Article Update - Eukaryotic Biology Course[edit]

All,

A course I am enrolled in is participating in the Wiki Education Program. I have chosen to select this argument, and plan to improve the "Ribosomal RNA modification" section. Katrinadiel (talk) 22:17, 11 February 2024 (UTC)[reply]
