Abstract

For all cells, a DNA double strand break (DSB) is a dangerous lesion that can have profound consequences for the genome. If a DSB is encountered during mitosis, chromosomal separation may be adversely affected. Alternatively, during S phase a DSB may cause replication fork stalling or collapse. Improperly repaired DSBs can result in chromosomal rearrangements, senescence or activation of apoptotic pathways. Cells have developed sophisticated recombination pathways to metabolize and repair DSBs quickly as well as the capacity to differentiate physiologically occurring breaks from life threatening lesions. The two major pathways of recombination repair are known as non-homologous end-joining (NHEJ) and homologous recombination (HR). In this review, we will discuss the detection, response, and repair of DSBs in eukaryotes.

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.
