Other claims from this paper (5)
- Association The bound-to-free ribosome ratio decreased as irradiation dose increased.
- Intervention effect Microsomal fraction yield did not differ significantly between nonirradiated and irradiated embryos except at 3 kR.
- Mechanism The authors concluded that 1 and 2 kR irradiation increased free ribosomes at the expense of bound ribosomes.
- Mechanism At 3 kR, the authors inferred ribosome degradation alongside detachment from membranes.
- Observation Membrane-like substance was visible in ethanol during RNA extraction only for irradiated samples.
