Assembly of TMV

(a) The process begins by the insertion of the hairpin loop formed by the initiation sequence of the viral RNA into the protohelix’s central cavity.(b) The RNA then intercalates between the layers of the protohelix, thereby ordering the disordered loop and trapping the RNA.(c) Elongation proceeds by the stepwise addition of protohelices to the “top” of the viral rod.
