HELP!! Proteins are manufactured by ribosomes in the cell. Which sequence correctly traces the location of: (1) where the ribosomes subunits are manufactured; (2) where ribosomes that manufacture proteins for export from the cell are found; and (3) where proteins are "repackaged" into vesicles for export from the cell?

(1) J (2) O (3) L
