Repair of hydrogen peroxide-induced single-strand breaks in Escherichia coli deoxyribonucleic acid
Open accessAbstract
Near-ultraviolet (300 to 400 nm) irradiation of L-tryptophan yielded H2O2 (a toxic photoproduct) that was selectively lethal for rec and polA1 Escherichia coli mutants. H2O2 treatment of cells resulted in the induction of single-strand deoxyribonucleic acid breaks. These breaks were repaired to only a small extent in polA1, recA recB, and recA mutants, but were efficiently repaired in wild-type strains. We conclude that H2O2 deoxyribonucleic acid lesions require both the polA+ and recA+ pathways for repair.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
