Talk:DNA

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

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

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)

Chirality/Handedness of the DNA structure

I would suggest that the lede (at least) include a mention that DNA typically is found in a right-handed double-helix structure. There is a mention buried deep in the article about an alternative structure of DNA being left-handed, but it is not explicitly stated in the article that its (typical DNA's) chirality is right-handed. A very common (overwhelmingly so — an overwhelmingly dominant) mistake in DNA depictions is showing DNA as left-handed (which I am sure irks the hell out of people who know it as right-handed). The images are correct on the handedness (but I notice you have to look closely to see it with these illustrations as the choice in depiction method lends to an easy optical illusion where it can appear either way; closer examination shows the depiction can only be right handed). The lay person may not find it important, but it may lend information to the casual lay reader to inadvertently know the difference. Those in chemistry not familiar with the genetics field will particularly take note of such information (they understand handedness and its significance). — al-Shimoni (talk) 22:58, 24 July 2013 (UTC)

Type II errors

So, how many nucleotides are there? Do we just have A,G,C and T? Really? Are you sure? - kk — Preceding unsigned comment added by 174.131.5.205 (talk) 04:37, 6 August 2013 (UTC)

Alternate DNA chemistry

The author confessed that he wrote the Arsenic DNA paper to expose flaws in peer-review at subscription based journals; see http://www.michaeleisen.org/blog/?p=1439

Please update the Alternate DNA chemistry section to reflect this. — Preceding unsigned comment added by 91.177.104.174 (talk) 10:00, 4 October 2013 (UTC)

Nevermind, I overlooked the third paragraph that makes it clear it was a real paper and he was not the author. Leaving the above here as the reference may be of some use. — Preceding unsigned comment added by 91.177.104.174 (talk) 10:07, 4 October 2013 (UTC)

1.10 Vibration

I will delete this subsection as it clearly falls into the category of original research. This has been deleted and undeleted before, but it should never have been added in the first place as it is way to specific and represents only a sub-sub selection on the extensive scientific literature on various type of vibration of DNA. If it belongs at all in Wikipedia it would be in a small part of a hypothetical article on DNA Dynamics.Somoza (talk) 14:52, 7 November 2013 (UTC)
