Damage-inducible DNA replication (iSDR) was followed in UV-irradiated E. coli uvr + and uvr B5. Owing to the inhibition of dimer excision in the former (caused by the metabolic treatment), both contained similar amounts of unexcised dimers. Since iSD

It has been shown earlier that the starvation of E. coli for both amino-acids and thymine applied prior to UV irradiation inhibits pyrimidine dimer excision without affecting cell survival after UV irradiation. In such cells pyrimidine dimers are tol

There is a difference in the extent of inhibition of thymine dimers (TT) excision in ultravioley (UV) irradiated cells of E. coli after preirradiation depression of protein and DNA syntheses induced by a simultaneous deprivation of essential amino ac

The absence of pyrimidine dimer excision after UV irradiation in rat cell line was confirmed. The possibility of excision repair system depression by acidification of medium with H3PO4 in HeLa cells has been proved. The results obtained by two differ

It had been found earlier that the excision repair mechanism in E. coli B/R Hcr+ could be depressed by preirradiation, amino acid and thymine starvation; such an interference proved to have no appreciable influence on survival after ultraviolet irrad

Chinese hamster V79 cells irradiated by split doses of ultraviolet light (2.5 + 5.0 J m-2) synthesize higher molecular weight DNA molecules than those irradiated by a single dose (5.0 or 7.5 J m-2). A second dose applied 8 h following the first one r

Excision of pyrimidine dimers with pH decreasing in UV irradiated HeLa cells can be depressed. This depression is independent of the UV dose within the investigated range. The excision capacity of HeLa repair system from absolute amount of excised di
