Image problems[edit]

I believe the image has an error. Both DNA strands in the image go into the same direction, whereas in reality one of the strands should go into the opposite position. Wilke 17:29, 13 Sep 2004 (UTC)

Replaced image with corrected one. Wilke 17:50, 13 Sep 2004 (UTC)
Actually, the current figure has at least three, maybe four errors. 1. The alleged T is missing the methyl group at the 5-position, so it's actually a U. 2. The C should have a double bond between the 5- and 6-carbons. 3. The G should have only a single bond between the 1-nitrogen and the 6-carbon (note the carbon that forms five bonds). 4. It's ambiguous, but in some cases at least it looks like the "5" is labelling the 4' rather than the 5' carbon. Josh Cherry 00:04, 14 Jan 2005 (UTC)
Also, "Hydrogen bond" is misspelled. Mdotley 19:46, 10 March 2007 (UTC)

In the picture there are supposed to be three H-bonds between C and G. Instead there are two. The middle one is a interaction between N and N. This is incorrect. Guanine is supposed to have a H attached to the N. This H makes the H-bond with the N of Cytosine

The way one strand was in the wrong direction also made all the hydrogen bonds go between the wrong functional groups. Narayanese 15:02, 26 October 2007 (UTC)

Redirect question[edit]

Why does the page for Talk:Nitrogenous base redirect to this page? - H. J. Hackenbacker 13:38, 9 August 2006 (UTC)

Xanthine[edit]

Is it really a nucleobase, part of RNA or DNA? I had the impression that it was just a precursor. Narayanese 15:02, 26 October 2007 (UTC) nvm

typographical error[edit]

there is still an error in the naming of the pseudouracil nucleobase in th table "Modified pyrimidine bases" by mistake the pseudouracil nucleobase is named uracil if though it is drawn right corrected
