摘要:: The variation of DNA repair activity during the cell cycle was studied by analysing the UV-stimulated DNA synthesis in cells synchronized in mitosis. This activity was detected both by autoradiography and by directly measuring the incorporation of tritiated thymidine in cells irradiated and incubated in the presence of hydroxyurea. Cells in all phases were found to be able to perform repair. However the activity appeared to be considerably lower in mitotic cells than in cell in other phases. Increasing values of repair capacity were observed in G1 cells, in mixed G2, S and M cells and in asynchronous cells. The relationship between these findings and data on survival rates in the same synchronized cells is discussed.
