ACTION SPECTRA IN ULTRAVIOLET WAVELENGTHS (150‐250 nm) FOR INACTIVATION AND MUTAGENESIS OF Bacillus subtilis SPORES OBTAINED WITH SYNCHROTRON RADIATION

TL;DR: The action spectra for mutation induction paralleled those for the inactivation, indicating that vacuum‐UV radiation induced lethal and mutagenic damages in the spore DNA.
Journal ArticleDOI

Absorption spectra of deoxyribose, ribosephosphate, ATP and DNA by direct transmission measurements in the vacuum-UV (150-190 nm) and far-UV (190-260 nm) regions using synchrotron radiation as a light source.

TL;DR: Results indicate that the absorption of the sugar‐phosphate group, rather than adenine, contributed to the increase below 170 nm in the absorption spectra of ATP and DNA.
Journal ArticleDOI

Wavelength Dependence of Inactivation and Membrane Damage to Saccharomyces cerevisiae Cells by Monochromatic Synchrotron Vacuum-uv Radiation (145-190 nm)

TL;DR: The theory that inactivation of wet cells by vacuum-uv radiation may be attributable to damage in the cell membrane initiated by the absorption of water molecules supports the expectation that above 210 nm the site of major lethal damage shifts to DNA.
Journal ArticleDOI

WAVELENGTH DEPENDENCE OF THE FORMATION OF SINGLE-STRAND BREAKS AND BASE CHANGES IN DNA BY THE ULTRAVIOLET RADIATION ABOVE 150 nm

TL;DR: The main conclusions are that the majority of single‐strand breaks were induced by the absorption of photon in the sugar‐phosphate group in the vacuum‐UV region and that the base changes were induced equally well by absorption in the Vacuum‐UV and in the far‐UV regions.
Journal ArticleDOI

Single-strand breaks in supercoiled DNA induced by vacuum-UV radiation in aqueous solution.

TL;DR: There was no indication that the direct absorption of photon by the DNA molecule plays an important role in the production of single‐strand breaks in the DNA of plasmid pBR 322.
