[Changes in the pyrimidine blocks of thymic DNA immediately after gamma irradiation of the animal in a sublethal dosage].
Pyrimidine clusters of thymus DNA were determined in normal conditions and 5-10 min after gamma-irradiation of rabbits with a dose of 2 Gy. It was shown that a relative content of isopliths I and II significantly increased and that of isopliths V and VIII decreased in the exposed DNA as compared to normal. When isopliths were divided into the components a relative content of C2T2 fragments significantly increased in the exposed DNA while that of CT3 and T5 decreased.
