==Overview==
==THE CRYSTAL STRUCTURE OF AN RNA OLIGOMER INCORPORATING TANDEM ADENOSINE-INOSINE MISMATCHES==
The X-ray crystallographic structure of the RNA duplex [r(CGCAIGCG)]2 has, been refined to 2.5 A. It shows a symmetric internal loop of two, non-Watson-Crick base pairs which form in the middle of the duplex. The, tandem A-I/I-A pairs are related by a crystallographic two-fold axis. Both, A(anti)-I(anti) mismatches are in a head-to-head conformation forming, hydrogen bonds using the Watson-Crick positions. The octamer duplexes, stack above one another in the cell forming a pseudo-infinite helix, throughout the crystal. A hydrated calcium ion bridges between the, 3'-terminal of one molecule and the backbone of another. The tandem A-I, mismatches are incorporated with only minor distortion to the backbone., This is in contrast to the large helical perturbations often produced by, sheared G-A pairs in RNA oligonucleotides.
