Indicate whether each of the following descriptions better applies to the cisternal maturation model (C) or the vesicle transport model (V) for the organization of the Golgi apparatus. Your answer would be a four-letter string composed of letters C and V only, e.g. CVCV.
( ) Golgi cisternae are static organelles.
( ) Golgi cisternae exchange material exclusively by retrograde vesicular transport.
( ) A cis Golgi cisterna becomes a medial cisterna which becomes a trans cisterna.
( ) Any protein that passes through the Golgi apparatus should be incorporated into transport vesicles several times.

The cisternal maturation model views the Golgi cisterna as dynamic structures that move through the Golgi stack with cargo in their lumen. In this model, retrograde transport is responsible for carrying Golgi resident proteins back to an earlier compartment as each cisterna matures. The vesicle transport model, in contrast, describes Golgi cisternae as static structures. In this model, forward-moving vesicles carry forward-moving cargo, and backward-moving vesicles retrieve escaped resident proteins.
