Abstract

cells growing under optimal conditions without exogenous stress. We found that spontaneous DNA replication errors in proliferating cells arose more frequently in subpopulations experiencing endogenous stresses, such as problems with proteostasis, genome maintenance, and reactive oxidative species production. The presence of these subpopulations of phenotypic mutators is not expected to affect the average mutation frequency or to reduce the mean population fitness in a stable environment. However, these subpopulations can contribute to overall population adaptability in fluctuating environments by serving as a reservoir of increased genetic variability.

  • These mutator subpopulations do not significantly impact the average mutation frequency or overall fitness of the population in a stable environment, but play a crucial role in enhancing population adaptability in fluctuating environments by providing a reservoir of increased genetic variability.

    “These mutator subpopulations do not significantly impact the average mutation frequency or the overall fitness of the population in a stable environment. However, they play a crucial role in enhancing population adaptability in fluctuating environments by providing a reservoir of increased genetic variability [78].”

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.
