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

Enzyme-free genetic copying of DNA and RNA sequences
Beilstein Journal of Organic Chemistry, 2018 The copying of short DNA or RNA sequences in the absence of enzymes is a fascinating reaction that has been studied in the context of prebiotic chemistry.

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.

Hfq CLASH uncovers sRNA-target interaction networks linked to nutrient availability adaptation
eLife, 2020 By shaping gene expression profiles, small RNAs (sRNAs) enable bacteria to efficiently adapt to changes in their environment. To better understand how Escherichia coli acclimatizes to nutrient availability, we performed UV cross-linking, ligation and ...

Manipulating a single adsorbed DNA for a critical endpoint [PDF]
, 2008 We show the existence of a critical endpoint in the phase diagram of unzipping of an adsorbed double-stranded (ds) polymer like DNA. The competition of base pairing, adsorption and stretching by an external force leads to the critical end point.

Change of Base in Bailey Pairs
The Ramanujan Journal, 2000 Versions of Bailey's lemma which change the base from q to q^2 or q^3 are given. Iterates of these versions give many new versions of multisum Rogers-Ramanujan identities. We also prove Melzer's conjectures for the Fermionic forms of the supersymmetric analogues of Virasoro characters.

Ribosomal 18S rRNA base pairs with mRNA during eukaryotic translation initiation
Nature Communications, 2016 Prokaryotic translation initiation involves mRNA-ribosomal RNA base pairing interactions. Here, the authors provide evidence for a similar base pairing interactions occurring between the human h4 mRNA and helix 16 of the small subunit rRNA to position ...

Pre-mRNA splicing is a determinant of nucleosome organization. [PDF]
PLoS ONE, 2013 Chromatin organization affects alternative splicing and previous studies have shown that exons have increased nucleosome occupancy compared with their flanking introns. To determine whether alternative splicing affects chromatin organization we developed
