Structural proteins which are spike (S), envelope (E) and membrane (M), therefor

Structural proteins which are spike (S), envelope (E) and membrane (M), therefore, in endoplasmic reticulum (ER) translation is carried out and then for the formation of virion, proteins go to the Golgi apparatus. Genomic RNA and viral structural proteins initially combined in cytoplasm where they are formed and assembled in nucleocapsids, which are then packaged into new viral particles filled with the viral genome. To discharge its virion, the infected cell uses exocytosis upon completion of the process.
