Abstract: | The incorporation of alternative functional components into nucleic acids can provide insight into what molecular features are necessary for an informational macromolecule to be successful. It can also provide a means to improve particular physical characteristics of nucleic acids for diagnostic and therapeutic purposes, or probe mechanisms. By testing the fitness of nucleic acid-like molecules derived by structural permutations of RNA, it may also prove possible to trace a path from simple prebiotic precursors to biotic molecules. This article describes the applications of 2',5'-phosphodiester linked, zwitterionic, and base-permuted nucleic acid derivatives. |
