Chapter 1:Complexes of Nucleic Acids with Group I and II Cations

Recent structures of large RNAs, such as the P4–P6 domain of the Tetrahymena ribozyme,1–5 and larger RNAs such as rRNAs,6–14 combined with a general increase over time in the sophistication of diffraction experiments, show cations in diverse and sometimes unexpected environments. The interactions of...
