Hoogsteen base pairs proximal and distal to echinomycin binding sites on DNA [PDF]
, 1987 Forms of the DNA double helix containing non-Watson-Crick base-pairing have been discovered recently based on x-ray diffraction analysis of quinoxaline antibiotic-oligonucleotide complexes.

The effect of RNA stiffness on the self-assembly of virus particles [PDF]
, 2017 Under many in vitro conditions, some small viruses spontaneously encapsidate a single stranded (ss) RNA into a protein shell called the capsid. While viral RNAs are found to be compact and highly branched because of long distance base-pairing between ...

Triplet Superconductors from the Viewpoint of Basic Elements for Quantum Computers [PDF]
, 2002 We discuss possibilities of utilizing superconductors with Cooper condensates in triplet pairing states (where the spin of condensate pairs is S=1) for practical realization of quantum computers.

Genome-wide double-stranded RNA sequencing reveals the functional significance of base-paired RNAs in Arabidopsis. [PDF]
PLoS Genetics, 2010 The functional structure of all biologically active molecules is dependent on intra- and inter-molecular interactions. This is especially evident for RNA molecules whose functionality, maturation, and regulation require formation of correct secondary ...

TurboFold: Iterative probabilistic estimation of secondary structures for multiple RNA sequences
BMC Bioinformatics, 2011 Background The prediction of secondary structure, i.e. the set of canonical base pairs between nucleotides, is a first step in developing an understanding of the function of an RNA sequence.

Identification of the base-pairing requirements for repression of hctA translation by the small RNA IhtA leads to the discovery of a new mRNA target in Chlamydia trachomatis. [PDF]
PLoS ONE, 2015 The non-coding small RNA, IhtA expressed by the obligate intracellular human pathogen Chlamydia trachomatis modulates the translation of HctA, a key protein involved in replicative to infectious cell type differentiation.

Coupled dynamics of RNA folding and nanopore translocation [PDF]
, 2005 The translocation of structured RNA or DNA molecules through narrow pores necessitates the opening of all base pairs. Here, we study the interplay between the dynamics of translocation and base-pairing theoretically, using kinetic Monte Carlo simulations

ARGONAUTE PIWI domain and microRNA duplex structure regulate small RNA sorting in Arabidopsis. [PDF]
, 2014 Small RNAs (sRNAs) are loaded into ARGONAUTE (AGO) proteins to induce gene silencing. In plants, the 5'-terminal nucleotide is important for sRNA sorting into different AGOs.
