(comment from August 2005)
I wanted sdto look up RNA in the wikipedia thinking that it would be able to give me a good starting point to understanding it. However, what I got was what's posted which tells me absolutely nothing as a newbie to genetics. Could someone please lay some ground rules about this kind of thing. It seems to me that since you can put lots of links in the definition of an entry, the entry loses it's coherence for someone like me. I think a good rule for wikipedia entries is that there should only be 3 links allowed in the opening general description paragraph of an article.
basically DNA the instructions for are organisms is found in the nucleus. however it can not leave the nucleus so when "instructions" need to be send out, part of the DNA is unraveled and copied. dna is made of four base pairs. i shall use just the letters A, T, C ang G. amazing yes that all life is described in changing patterns of these. A always pairs with T and C with G. because DNA is two strands. when copying dna the two strands are unraveled and one side is copied because if know one side you know the other. RNA bases (the same as DNA bases except use U instead of T) go into the nucleus and bind to the complimentary DNA bases. They then polymerise into the RNA strand. This is transcription. If it is a mRNA then it is later translated into protein.
that is the most basic explaination without getting into virii and other things.
Loads of prebiotic molecules found in Milky Way?
FWIW - (For being aware only of newly published relevant studies - not necessarily to incorporate into the main article) - On 8 July 2022, astronomers reported the discovery of massive amounts of prebiotic molecules, including for RNA, in the galactic center of the Milky Way Galaxy. - Stay Safe and Healthy !! - Drbogdan (talk) 13:09, 10 July 2022 (UTC)

double stranded molekul by default?
Just looking superficially at the images in the article, one can think that RNA is a (mostly) double stranded molecule. however, that is not true as far I know. I think at least, first image should be a single stranded RNA image. Araz Zeyniyev (talk) 02:41, 2 January 2023 (UTC)
Too technical first sentence
The first sentence leans on very specialized terms.
Abbreviated: RNA is essential in various biological roles in coding, decoding, regulation and expression of genes.
In the first sentence we should strive to convey the essentials in a way that many can understand. Here is a trial:
RNA is essential for all biological functions, either by performing that function itself (Non-coding RNA) or by forming a template for production of proteins (messenger RNA). Ettrig (talk) 08:00, 5 July 2023 (UTC)
Better introductory picture
Here is a good introductory picture for RNA. The site says that it is public domain. Ettrig (talk) 08:55, 5 July 2023 (UTC)
