 This connecting structure serves as a transportation "highway" for the viral ribonucleoprotein (RNP).Thus, RNP travels through the connecting structure to reach the cell interior allowing SeV genetic material to enter the host cell cytoplasm.Once in the cytoplasm, the SeV genomic RNA is getting involved, as a template, in two different RNA synthetic processes performed by RNA-dependent RNA polymerase, which consists of L and P proteins
