Abstract:
In normal human fibroblasts we observe an enhancement of the recovery of the rate of semi-conservative DNA synthesis after split-dose UV-irradiation relative to a single total UV dose. The enhanced recovery is totally absent in both a xeroderma pigmentosum variant line and two xeroderma pigmentosum lines belonging to complementation groups A and C.
