Abstract

Ultraviolet radiation is common to most planetary environments and could play a key role in the chemistry of molecules relevant to abiogenesis (prebiotic chemistry). In this work, we explore the impact of UV light on prebiotic chemistry that might occur in liquid water on the surface of a planet with an atmosphere. We consider effects including atmospheric absorption, attenuation by water, and stellar variability to constrain the UV input as a function of wavelength. We conclude that the UV environment would be characterized by broadband input, and wavelengths below 204 nm and 168 nm would be shielded out by atmospheric CO2 and water, respectively. We compare this broadband prebiotic UV input to the narrowband UV sources (e.g., mercury lamps) often used in laboratory studies of prebiotic chemistry and explore the implications for the conclusions drawn from these experiments. We consider as case studies the ribonucleotide synthesis pathway of Powner et al. (2009) and the sugar synthesis pathway of Ritson and Sutherland (2012). Irradiation by narrowband UV light from a mercury lamp formed an integral component of these studies; we quantitatively explore the impact of more realistic UV input on the conclusions that can be drawn from these experiments. Finally, we explore the constraints solar UV input places on the buildup of prebiotically important feedstock gasses like CH4 and HCN. Our results demonstrate the importance of characterizing the wavelength dependence (action spectra) of prebiotic synthesis pathways to determine how pathways derived under laboratory irradiation conditions will function under planetary prebiotic conditions.

  • DNA is most damaged by wavelengths shorter than 290 nm.

    “However, it has been observed that wavelengths below 290 nm are most damaging to DNA, and that the Archean Earth would have experienced a higher flux of shorter-wavelength UV radiation though water and atmospheric carbon dioxide may have efficiently blocked wavelengths much below 200 nm (Cockell 1998;Ranjan and Sasselov 2016).”

  • UV is thought to have played a significant role in prebiotic synthesis, including the synthesis of uracil and cytosine.

    “Despite UV's potentially deleterious effects on life, UV is thought to have played a significant role in prebiotic synthesis (eg., Ranjan and Sasselov 2016;Beckstead et al. 2016;Sutherland 2017), and plays a key role in the prebiotic synthesis of uracil and cytosine achieved by Powner et al. (2009), an important achievement in understanding the prebiotic emergence of RNA.”

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.
