Abstract

Possibly the earliest enzymatic activity to appear in evolution was that of the polynucleotide polymerases, the ability to replicate the genome accurately being a prerequisite for evolution itself. Thus, one might anticipate that the mechanism by which all polymerases work would be both simple and universal. Further, these enzymatic scribes must faithfully copy the sequences of the genome into daughter nucleic acid or the information contained within would be lost; thus some mechanism of assuring fidelity is required.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Crystal structures reveal that polymerase binding to DNA strongly reshapes the primer-template, for example the backbone at the templating base can be bent by 90°.

    “Crystal structures (Refs.15-22 and references therein) reveal that polymerase binding to DNA strongly reshapes the primertemplate, e.g. the backbone at the templating base can be bent by 90°.”

  • Polymerases in families A, B, X, and RT have nascent base pair binding pockets that tightly accommodate a correct Watson-Crick base pair.

    “Polymerases in families A, B, X, and RT have nascent base pair binding pockets that tightly accommodate a correct Watson-Crick base pair (Fig. 2A and additional images in Refs.15-19 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.
