== Comments from Neelix == 

 I am impressed with the work you have been doing on this article. Here are some recommendations for further improvement: 

 #There should be no need to include any citations in the lead as the lead should only be a summary of the body. 
 #All information should be sourced; much of the first paragraph of the "Discovery" section is currently unsourced, as are other portions of the article. 
 #DNA base currently redirects to the Nucleobase article, but there is no mention of the term "nucleobase" on this article, nor is there any mention of the terms "DNA base" or "DNA base flipping" on the Nucleobase article. Can the connection between these concepts be clarified somehow? Are "nucleobase" and "DNA base" synonyms? 
 #This article currently has only two incoming links from other Wikipedia articles. I would recommend linking to this article from other articles, either manually or by adding a relevant navbox. You may wish to consider whether or not this navbox would be suitable. 
 #In order to be considerate of users with visual impairment, it would be beneficial to add alternative text to the images. 
 #Any other Wikipedia article linked in the body of this one should only be linked once, but some are currently linked more than once, such as DNA, Haemophilus haemolyticus, RNA polymerase, etc. 
 #The article would look better if the lead image was moved to the top of the article so that the image and text of the lead were side-by-side. 

 Thank you for doing such great work with this article. Please let me know if you have any questions about the above.
