Using agarose gel electrophoresis and \u201creversed phase\u201d HPLC technique ssb, dsb induction and uracil formation, respectively, could be detected in the irradiated DNA in dependence on the UV fluence. The analysis of the strandbreaks in bifilar Col E1 DNA shows a significant part of directly induced dsb. <\/jats:p>\n               <jats:p>Cross sections of ssb induction from 4.1 m<jats:sub>2<\/jats:sub>\/J x 10<jats:sup>7<\/jats:sup> in 28%, 3.9 m<jats:sup>2<\/jats:sup>\/J x 10<jats:sup>7<\/jats:sup> in 55% and 3.1 m<jats:sup>2<\/jats:sup>\/J x 10<jats:sup>7<\/jats:sup> in 8 5 -9 0% BU-substituted DNA were calculated. The cross section for dsb induction was found to be 0.04 m<jats:sup>2<\/jats:sup>\/J x 10<jats:sup>7<\/jats:sup>, estimated from the linear part of the fluence effect curve. In monofilar M13 DNA a linear fluence effect curve for dsb induction was obtained. Excluding other than the direct production of dsb by using an in vitro approach for M13 DNA , the results strongly support the hypothesis that dsb can be induced by one photochem ical absorption event.
