2'-Deoxy-3-isoadenosine Forms Hoogsteen-Type Base Pairs with Thymidine in the d(CG[iA]TCG)_2 Duplex^1

Abstract

Present-day genetic material, DNA and RNA, consists of five major nucleic acid bases (A, G, T, C, and U) and the sugar-phosphate backbone. In addition to the question of their selection from prebiotic matter, there are more subtle issues, including, in the case of purines, the site of attachment of ribose/deoxyribose at N9 versus N3. The reaction of adenine with protected sugar halides gives a mixture containing more or less equal amounts of N9 and N3 derivatives.
