Recovery from DNA synthesis in V 79 chinese hamster cells irradiated with UV light; Recuperacao de sintese de DNA em celulas V79 de hasmter chines irradiadas com luz ultravioleta

Abstract

Mammalian cells recover from DNA synthesis inhibition by UV light before most of the pyrimidine dimers have been removed from the genome. Most of the rodent cells show a deficient dimer excision repair compared with normal human fibroblasts. Despite this fact they recover efficiently from DNA synthesis inhibition after UV. In Chinese hamster V 79 cells was found that this recovery takes place in the absence of a significant excision repair, and it seems to be directly coupled to a recovery in the rate of movement of the replication fork. 120 refs, 31 figs. (author).
