Growth of TMV coat protein rods

Aggregation state of TMV coat protein(a)(b)34š$$›i6F„œWf=¸ª•ž„ßßâš$›i6FŸ~(c)(a) The process begins by the insertion of thehairpin loop formed by the initiation sequence ofthe viral RNA into the protohelix’s central cavity.
(b) The RNA then intercalates between thelayers of the protohelix, thereby ordering thedisordered loop and trapping the RNA.
(c) Elongation proceeds by the stepwise additionof protohelices to the “top” of the viral rod.
