1. Introduction 2222. What is an RNA motif? 2222.1 Sequence vs. structural motifs 2222.2
RNA structural motifs 2232.3 RNA structural elements vs. motifs 2232.4 Specific recognition …

Guanine's array of hydrogen bond donors and acceptors lead it to take part in structures as
diverse as B-DNA, Z-DNA, hairpins, cruciforms, triplexes, and G-quadruplexes; these …

Nucleic acids are potent triggers for innate immunity. Double‐stranded DNA and RNA adopt
different helical conformations, including the unusual Z‐conformation. Z‐DNA/RNA is …

RNA plays myriad roles in the transmission and regulation of genetic information that are
fundamentally constrained by its mechanical properties, including the elasticity and …

Despite structural differences between the right-handed conformations of A-RNA and B-
DNA, both nucleic acids adopt very similar, left-handed Z-conformations. In contrast to their …

The addition of poly (UG)('pUG') repeats to 3′ termini of mRNAs drives gene silencing and
transgenerational epigenetic inheritance in the metazoan Caenorhabditis elegans. pUG tails …

The A form RNA double helix can be transformed to a left-handed helix, called Z-RNA.
Currently, little is known about the detailed structural features of Z-RNA or its involvement in …

The surfaces of colloidal nanocrystals are complex interfaces between solid crystals,
coordinating ligands, and liquid solutions. For fluorescent quantum dots, the properties of …

The database of RNA structure has grown tremendously since the crystal structure analyses
of ribosomal subunits in 2000–2001. During the past year, the trend toward determining the …

The left-handed Z-conformation of nucleic acids can be adopted by both DNA and RNA
when bound by Zα domains found within a variety of innate immune response proteins. Zα …
