Abstract

Significance: Clustered, regularly interspaced, short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide adaptive immunity for bacteria and archaea. They use a protein complex that targets invading nucleic acids using a bound RNA that hybridizes to complementary sequence stretches. On DNA targets, the resulting structure is an R-loop. By twisting single DNA molecules, we can directly observe R-loop formation and dissociation in two distinct types of CRISPR-Cas system. This allows us to investigate the role of different elements of the target sequence. Whereas upstream elements control the actual R-loop formation, downstream elements ensure R-loop stability, suggesting a directional R-loop formation. This provides insight into the recognition process by these enzymes, which is the crucial step to understand targeting in the rapidly emerging genetic engineering applications of CRISPR-Cas systems.

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.
