when the cells equilibrated with a certain saline medium were labelled with [ 3h ] uridine for 15 min and their cationic equilibrium was changed by another equilibration in a medium having a different na+/k+ ratio , the processing of labelled heterogenous nuclear rna was drastically changed , i.e . part of the labelled rna was rapidly depolymerized , while the other part was deposited in the nuclei or cell cytoplasm .
