Uncoupling of Leading- and Lagging-Strand DNA Replication During Lesion Bypass in Vivo

Pagès, Vincent, Fuchs, Robert P.·2003·Science

Abstract

Numerous agents attack DNA, forming lesions that impair normal replication. Specialized DNA polymerases transiently replace the replicative polymerase and copy past lesions, thus generating mutations, the major initiating cause of cancer. We monitored, in Escherichia coli , the kinetics of replication of both strands of DNA molecules containing a single replication block in either the leading or lagging strand. Despite a block in the leading strand, lagging-strand synthesis proceeded further, implying transient uncoupling of concurrent strand synthesis. Replication through the lesion requires specialized DNA polymerases and is achieved with similar kinetics and efficiencies in both strands.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Primer relocation and active site misalignment can both result in primer termini with one or more correct base pairs, thereby allowing more efficient polymerization following insertion of an incorrect nucleotide or insertion opposite a lesion.

    “Primer relocation and active site misalignment can both result in primer termini with one or more correct base pairs, thereby allowing more efficient polymerization following insertion of an incorrect nucleotide or insertion opposite a lesion (Refs.15, 56, 57, 59 and references therein).”

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.
