1. Within experimental chromatin, the total protein: DNA ratio did not vary in, the same organs of control and irradiated rats. However, the amount of RNA and total protein associated with the DNA varied considerably among the different types of chromatin.
In particular, the content of chromatin was the highest in the irradiated tissue, and the lowest in the chromatin control tissue. RNA and total
protein ratio of chromatins from brain, liver, testis and spleen declined with experimental
organs.
2. There was the same quantitative relationship between the amount of RNA : and the amount histone-protein associated.- with DNA i-in..each chromatin.
3. RNA: DNA ratio of chromatin, showed,a 1.5^2 times increase in the irradiated organs except brain. However, RNA: DNA ratio was decreased in chromatin by irradiation.
4. Histone-protein: Residual protein ratio was greatly varied among the organs. However, the effect was not found by irradiation.
