Proposed merger[edit]

I'm proposing that Thymine dimer be merged into this page. All the information on the thymine dimer page is pertinent for other pyrimidine dimers. While thymine dimers are the most commonly formed, CT dimers and CC dimers are also formed at significant rates [1], and the CC and CT dimers are actually more likely to result in mutations due to the "A rule" that causes As to be inserted when the template is doubtful[2]. I can add the material from Thymine dimer to this page and then add a discussion based on the references above, and I think it will be more informative than having the two articles separate.

Okay, I've set up a draft of the proposed new Pyrimidine Dimer page here: User:Agathman/CPDs_Working_Page. There has been no comment since the merger proposal went up, almost 3 months ago, so I'm about ready to replace the Pyrimidine dimer page with my draft and replace the Thymine dimer page with a redirect to that one. If anyone cares, please say so soon.
Sounds good. I will rescue the highly chemical bit abuot cyclobutanes. Thymine dimer is not very impressive as it stands, so your work is a real improvement.--Smokefoot (talk) 16:23, 16 August 2009 (UTC)

Although this article is about a technical subject, the lead should be made easier to understand. For example, the word “translesion,” although correct, is not in the dictionary. Bwrs (talk) Bwrs (talk) 03:34, 1 December 2009 (UTC)

Not 6-4 and left handed DNA[edit]

In the figure illustrating the types of dimers, 6-4 photoproduct is shown incorrectly. What is shown is a so-called "spore photoproduct" ( The structure of 6-4 is quite different (, Fig. 15.2) —Preceding unsigned comment added by (talk) 11:44, 12 June 2010 (UTC)

The SP product is okay according to 2006 paper by Buis et al ... doi:10.1074/jbc.M603931200. Your ref ( gets its structure for Figure 15.2 from Taylor et al J Am Chem Soc. 1987; 109: 2834–2835, which might be obsolete. Medical sources occasionally are way behind on their chemistry.--Smokefoot (talk) 01:24, 16 November 2010 (UTC)

The image 'DNA_UV_mutation.svg‎' shows a left-handed DNA, it should be a right handed DNA. This a fundamental mistake.

Assessment comment[edit]

The comment(s) below were originally left at Talk:Pyrimidine dimer/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

The final diagram is in error. The ring double bonds in the thiamines have remained, despite the formation of the dimer. I am not expert enough to know the exact arrangement, but do know that 5-bonnded carbon is wrong. I agree, there should not be a double bond in the ring of the two thymine dimers anymore. Someone needs to edit the diagram. —Preceding unsigned comment added by (talk) 17:17, 10 December 2007 (UTC)
