Photobiological Origins of the Field of Genomic Maintenance

Abstract

Although sunlight is essential for life on earth, the ultraviolet (UV) wavelengths in its spectrum constitute a major threat to life. Various cellular responses have evolved to deal with the damage inflicted in DNA by UV, and the study of these responses in model systems has spawned the burgeoning field of DNA repair. Although we now know of many types of deleterious alterations in DNA, the approaches for studying them and the early mechanistic insights have come in large part from pioneering research on the processing of UV‐induced bipyrimidine photoproducts in bacteria. It is also notable that UV was one of the first DNA damaging agents for which exposure was directly linked to cancer; the sun‐sensitive syndrome, xeroderma pigmentosum, was the first example of a cancer‐prone hereditary disease involving a defect in DNA repair. We provide a short history of advances in the broad field of genomic maintenance as they have emerged from research in photochemistry and photobiology.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • DNA and RNA are damaged by both ultraviolet and ionizing radiation.

    “Both UV and ionizing radiation damage DNA and RNA.”

  • Radiation exposure would significantly challenge the development of an early nucleotide-based system because radiation damage harms the stability and fidelity of genetic material.

    “Because radiation damage has strong negative consequences for the stability and fidelity of genetic material (Ganesan and Hanawalt 2016;Kladwang et al. 2012), radiation exposure would present a significant challenge in the development of an early nucleotide-based system.”

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.
