RNA polymerisation capacity and permeability to ribonucleoside triphosphates of nuclei from livers of whole-body X-irradiated rats.
For 4--18 h following whole-body X-irradiation of rats, liver nuclei showed a progressive increase in the permeability to ribonucleoside triphosphates (as assessed in vitro using tritiated uridine triphosphate (UTP) and in the capacity to polymerise RNA in vitro (Mg++-containing and Mn++/(NH4)2SO4-containing assay systems).
