Although degradation by Cas3 handicaps the invader, it might not lead to full destruction of the target; complete degradation might be induced by other cellular nucleases or by Cascade-independent Cas3 nuclease activity.
“Although this degradation handicaps the invader, it might not lead to the full destruction of the target. Complete degradation might be induced by other cellular nucleases or by Cascade-independent Cas3 nuclease activity, which has been previously documented [44,45,46].”
From CRISPR-Cas: Converting A Bacterial Defence Mechanism into A State-of-the-Art Genetic Manipulation Tool (2019) · cites this paper as [45]
The linear-DNA experiments report that Cas3 degradation proceeds upstream from the protospacer and leaves downstream DNA intact, supporting the possibility that Cas3 does not fully destroy a target. The paper does not propose that other cellular nucleases complete degradation or document Cascade-independent Cas3 degradation of the target; its experiments describe target degradation as Cascade-dependent.

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.
