using 3h-fucose as a tracer and the radioautographic technique , we observed that the golgi apparatus incorporates the tracer and delivers the labeled glycoproteins to the developing acrosomic system during steps 1-7 of spermiogenesis , to multivesicular bodies during steps 1-9 , and to the remaining cytoplasm and plasma membrane during steps 1-15 .
