Abstract
Using an acellular system, with isolated chromatin as a template, and E. coli RNA-polymerase it was shown that irradiation of rats with a lethal dose (7.76 Gy) caused a progressing, in time, decrease in the inhibitory effect of H1, H2a, H2b, H3 and H4 histones (particularly H2a histone) on RNA synthesis. The administration of serotonin prior to irradiation diminished considerably this effect of radiation.
