Nakano et al. use high-speed AFM and cryo-EM to study influenza virus RNA synthesis in vitro. They observe the synthesis of two types of RNA: folded single stranded RNA associated to an intact viral ribonucleoprotein (vRNP) and looped, double stranded RNA associated with a partially rearranged vRNP structure.
