人们对DNA的辐射损伤效应已作了较为深入的研究,然而,在真核生物的染色质内,DNA与组蛋白、非组蛋白是紧密结合在一起以核蛋白的形式存在的,核蛋白复合物具有高度的辐射敏感性已为人们所公认。因此,在谈到细胞的辐射损伤时,不仅是DNA,还必须考虑到与DNA密切结合的染色质蛋白,其中组蛋白 The effects of radiation damage on DNA have been studied in depth. However, within the chromatin of eukaryotes, DNA and histones and non-histones are tightly bound together in the form of nuclear proteins. Nucleoprotein complexes exist. It has been recognized that the material has a high degree of radiation sensitivity. Therefore, when it comes to radiation damage to cells, not only DNA, but also chromatin proteins that bind closely to DNA must be considered, including histones.
