M. F. Wilkins, Erwin Chargaff and Raymond Gosling's photos added[edit]

Not only Professor Wilkins's photo should be present but also

Professor Raymond Gosling's, Erwin Chargaff's, as well as the photos of Herbert Wilson. F.R.S. and Alex Stokes should also be present; however, the latter two were unavailable at this point for Wikipedia use, and if made available it is important that they also should be added because of their very important role played in the X-ray+molecular modeling analysis of DNA saga.

Rosalind Franklin[edit]

Why is there no credit given to Rosalind Franklin? 21:50, 5 July 2013‎ User:82.26.207.27

I agree - she has her own Wiki entry that acknowledges her contribution to the structure of DNA "According to Francis Crick, her data was key to determining the structure[3] to formulate Crick and Watson's 1953 model regarding the structure of DNA." but there is no mention of her work on the actual DNA site. — Preceding unsigned comment added by 194.60.106.5 (talk) 14:52, 4 October 2013 (UTC)

She is credited in the History section. But I don't know why her picture was removed. danielkueh (talk) 15:26, 30 December 2013 (UTC)

The history section suggests that Franklin and Gosling's work was merely in support of Watson and Crick, but from my "what's available on the web" based research suggests that this is not right -- Watson was shown Franklin's data, which Watson and Crick used as the basis for, at least the specifically described shape of the DNA structure. When presented to Franklin, she may have been lead to think that her work merely confirmed Watson and Crick's (which is reflected in her paper) model building approach, but she was basically looking at her own work, with a few addenda which encoded Chargaff's rules. The description in the history section appears to be written contrary to this. Qed (talk) 22:56, 21 March 2014 (UTC)

Gene control[edit]

A discovery about another function of DNA has been discovered. Article here. It seems that this code is written in binary. --Artman40 (talk) 13:42, 13 December 2013 (UTC)

Genetic recombination[edit]

I don't get this diagram (as of March 20, 2014). It looks like A is paired with G, and C paired with T, which is wrong. 128.174.127.111 (talk) 15:24, 21 March 2014 (UTC)

It's showing different chromosomes, not the paired sequences in one chromosome. (Each chain shown would be paired with the complementary nucleobase.) Mindmatrix 16:35, 21 March 2014 (UTC)

Editing and exobiologist[edit]

Hello all. I wanted to hyperlink the term "exobiologist" to the article "Astrobiology", but the article is unavailable to anonymous editing. So I made an account and the article is still not editable to me....

Can someone hyperlink "exobiologists"--I didn't know what it meant. And, explain why I still can't edit the article? — Preceding unsigned comment added by Exoedit (talkcontribs) 18:19, 2 May 2014 (UTC)

You're welcome. I added the link. Semi-protected pages like this can only can be edited by new users who registered more than 4 days before and have made 10 other edits. Bever (talk) 02:58, 5 July 2014 (UTC)

Prime[edit]

Could someone add why the symbol "prime" is used in 5' and 3' ? Why not simply 5 and 3 ? Thanks in advance. --91.179.219.82 (talk) 18:41, 17 August 2014 (UTC)
