Reactions of OH radicals with poly(U) (polyuridylic acid) in the presence of Ru(bpy)32+ or Ru(phen)32+ in aqueous solutions were studied. OH radicals were produced by pulse radiolysis and their reactions with ruthenium complexes were measured spectro

It was found that incubation of ?-irradiated or DNaseI-treated plasmid DNA in a protein extract of Escherichia coli leads to enzyme-induced formation of double strand breaks (dsb) in competition with repair of precursors of these dsb. A survival curv

Double-strand breaks (dsbs) have been produced in plasmid DNA by various restriction endonucleases and the survival and the deletion mutation incidence have been measured in E. coli. The deletion formation is known to depend upon the occurrence of sh

The reactions of several five-membered oxygen and nitrogen heterocyclics with OH • and SO 4 •− radicals have been investigated in aqueous solution using in-situ radiolysis and photolysis ESR, and optical and conductometric pulse radiolysis tech

In situ photolysis at 20 degrees C (argon plasma light source, lambda approximately greater than 200 mm) of oxygen-free solutions containing 2 mM H2O2 and heat-denatured, single-stranded (ss)DNA from calf-thymus resulted in the ESR spectra of the 6-h

Laser excitation of DNA in aqueous solution leads to biphotonic formation of base radical cations and solvated electrons in addition to monophotonic products. The chemical pathways from the radical cations to strand breakage for several polynucleotid

The photoreaction of 2-methyl-1,4-naphthoquinone (MQ, menadione) with DNA and polynucleotides in argon-saturated aqueous solution (pH 7) was studied. Results from laser flash photolysis experiments indicate that triplet quinone reacts with DNA and po
