Abstract

Transcription requires that RNA polymerase binds to promoters buried in nonspecific sites on DNA. The search for promoters may be facilitated if the polymerase slides along the molecule of DNA. Single molecules of Escherichia coli RNA polymerase were visualized, and their movements on immobilized bacteriophage λ and T7 DNAs were examined. Deviating from drifts by bulk flow, about 40 percent of the enzyme molecules moved along the extended DNA. The results provide direct evidence for sliding as a mechanism for relocation of the enzyme on DNA.

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.
