摘要：

The repair times of X-ray-induced chromosomal breaks produced at different stages of the cell cycle were studied. Human peripheral lymphocyte cultures were used because of their relative" synchronous character. The repair time in G1 and S was observed to be 90 min. In late S and G2 the repair time was 60 min. The 30-min decrease in repair time in G2 was thought to be due to a change in the repair system itself rather than the cell's commitment to division. The possibility that repair efficiency may well be dictated by factors preceeding the repair act is discussed. © 1969."
