The problem of the relation between blood groups and disease has been the subject of many investigations. An important paper appeared as early as 46 years ago (Buchanan and Higley, 1921). Specific studies about blood groups and leprosy also date back to the twenties (Puente, 1927-28 and others).

Here we describe the crystal structure of modified [d(CGCGAATTCGCG)]2 refined to 2.04 A. The modification, which affects only the two thymines at the central ApT step, involves isosteric removal of the 2-keto oxygen atoms and substitution of the N1 nitrogen with carbon. The crystal structure reveals the ability of this modified thymine to effectively base pair with adenine in [d(CGCGAAtTCGCG)]2...
