T7 RNA polymerase functions in vitro without clustering. [PDF]
PLoS ONE, 2012 Many nucleic acid polymerases function in clusters known as factories. We investigate whether the RNA polymerase (RNAP) of phage T7 also clusters when active.

First High-Resolution Crystal Structures of DNA:2′-O-Methyl-RNA Heteroduplexes
Crystals, 2022 Heteroduplexes composed of all-DNA and all-2′-OMe RNA strands do not occur in nature, but they have found application in the development of molecular beacons and could also be used as aptamers or elements of nucleic acid-based nanostructures that will ...

Microgels and apparatus for PAGE of nucleic acids in one or two dimensions
BioTechniques, 2018 We describe a system for horizontal 1D or 2D PAGE comprising an apparatus and microgels. There is no buffer outside the gel, making handling and sample loading easy.

The telomerase essential N-terminal domain promotes DNA synthesis by stabilizing short RNA-DNA hybrids. [PDF]
, 2015 Telomerase is an enzyme that adds repetitive DNA sequences to the ends of chromosomes and consists of two main subunits: the telomerase reverse transcriptase (TERT) protein and an associated telomerase RNA (TER). The telomerase essential N-terminal (TEN)

Nanosecond chain dynamics of single-stranded nucleic acids [PDF]
arXiv, 2023 The conformational dynamics of single-stranded nucleic acids are fundamental for nucleic acid folding and function. However, their elementary chain dynamics have been difficult to resolve experimentally. Here we employ a combination of single-molecule F\"orster resonance energy transfer, nanosecond fluorescence correlation spectroscopy, fluorescence ...
