G-quadruplexes

RNA Sequences Don’t Predict In Vivo Transcript Structure
Catherine Offord | Jan 1, 2017
Eukaryotes prevent secondary RNA structures called G-quadruplexes, commonly observed in vitro, from forming in the cell. 
Infographic: Keeping RNA Structures in Line
Catherine Offord | Dec 31, 2016
Scientists find fewer RNA G-quadruplexes in vivo than in vitro.
