Screening of Minimalist Noncanonical Sites in Duplex DNA and RNA Reveals Context and Motif-Selective Binding by Fluorogenic Base Probes. The collective data reveal pairing propensities in base organization, secondary structural context, and deformability and serve as a starting point for further multiscale investigations and/or simulations of RNA folding. Non-canonical base pairing occurs when nucleobases hydrogen bond, or base pair, to one another in schemes other than the standard Watson-Crick base pairs (which are adenine (A) -- thymine (T) in DNA, adenine (A) -- uracil (U) in RNA, and guanine (G) -- cytosine (C) in both DNA and RNA). A probabilistic approach was applied, and an algo-rithm and its implementation in a computer program that detects and analyzes all the base pairs contained in RNA 3D structures were developed.
