Summary
Incorporation of 5-bromodeoxyuridine (BUdR) sensitizes the inactivability by UV of transforming DNA of Bacillus subtilis. The sensitization towards monochromatic UV between 230 and 350 nm has been studied for unifiliarly and bifiliarly substituted DNA. The results for irradiation with UV of 230 and 320 nm indicate that unifiliarly substituted DNA (TB) behaves like a one-to-one mixture of unsubstituted (TT) and bifiliarly substituted (BB) DNA. Since this is in accordance with what has been found (for longwave UV only) for phage λ we believe the result for 320 nm irradiation to mean that the UV induced lesions within the substituted strand interfere with the transcription rather than with the replication mechanism. This picture seems to be conclusive for phage λ and is in contrast to what is known about the lesions induced in unsubstituted DNA by UV of 260 nm.
The inactivation curve for TB for irradiation with UV of 260 or 290 nm simulates a one-to-one mixture of TT and BB only down to about 10% survivors. With higher doses the survival is lower than expected for a one-to-one mixture. This could indicate that at higher doses small amounts of photoproducts are produced in which both strands are involved.
In contrast to phage λ transforming DNA will give the above results without a radioprotective substance. It is discussed in how far, in the case of phage λ, the greater local DNA concentration and the protein coat can be the reason for this difference.
