Elevated recombination rates in transcriptionally active DNA

Open access
Thomas, Barbara J., Rothstein, Rodney·1989·Cell

Abstract

We have examined the effect of RNA polymerase II-dependent transcription on recombination between directly repeated sequences of the GAL10 gene in S. cerevisiae. Direct repeat recombination leading either to plasmid loss or conversion was examined in isogenic strains containing null mutations in the positive activator, GAL4, or the repressor, GAL80. A 15-fold increase in the rate of plasmid loss is observed in cells constitutively expressing the construct compared with cells that are not. Conversion events that retain the integrated plasmid are not stimulated by expression of the repeats. Northern analysis of strains containing plasmid inserts with various promoter mutations suggests that the stimulation in recombination is mediated by events initiating within the integrated plasmid sequences.

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.
