Indicate Whether Each of the Following Descriptions Better Applies to the Cisternal

Short Answer

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.
