Assembly of icosahedral virus particles from the constituent capsids. (a) Schematic view of a virus particle with dimeric subunits and RNA genome. The expanded view displays the molecular structure of the subunit with one of its RNA binding domains. (b) Evolution of the SAXS intensity during the assembly process. The cartoon shows the rapid binding of subunits onto the genome and then the slow reorganization of the complex to the final structure. (c) Arrhenius plot of the binding time constant (${\tau }_{bind}$) deduced from low q SAXS intensity at different temperatures, which provided an estimate of the activation energy ($E_a$).
