TL;DR: In this article, an A.G.G tetrad was identified for the d(G-G-A-G, A-G -G, G-A -G-N) sequence in 150 mM Na(+) (or K(+)) cation solution where four symmetry-related strands align into a novel dimeric motif.

TL;DR: The structure of the quadruplex contains internal cavities that can potentially accommodate Na cations positioned between adjacent tetrad planes and the potential role of quadruplex formation involving G.G.C.C tetrads during the integration of the adeno-associated parvovirus into its target on human chromosome 19, both of which involve stretches of G-G- G-C sequence elements.

TL;DR: The first examples of the specifically 15N and 13C multilabeled nucleosides are reported, which allow the N1 and N2 15N atoms of two 15N-labeled guanines to be unambiguously differentiated in RNA and DNA fragments.

TL;DR: This paper outlines site-specific labeling approaches to identify slowly exchanging imino(guanine) and amino (Guanine and adenine) protons in internal loop and bulge segments of compact RNA folds such as found in the AMP–RNA aptamer complex.

TL;DR: In this article, it was shown that the N 1-methoxy derivatives of adenosine and 2-deoxyadenosine undergo a Dimroth rearrangement in which the intermediate N,N-dimethylamino adducts are stable compounds.
