So, once on the CIS side of the Golgi apparatus, which is this side here, it basically moves along the Golgi apparatus. And as it moves, that particular N linked sugar molecule is even further modified. And on top of that, we also form the old glycosytic linkages between either the serene and threatening and that particular sugar molecule. And this takes place inside the Golgi apparatus. So inside the Golgi, we form the old linkages and we also continue modifying those sugars which have been formed via the end linkages. And once they essentially end up on the trans side of the Golgi apparatus.
