Thermal denaturation of B. subtilis DNA in H2O and D2O observed by electron microscopy.
In the present work we studied the initial part of thermal denaturation curves of B. subtilis DNA in normal and heavy water, observing, by electron microscopy, the "opening" of DNA as a function of temperature. The results support the hypothesis that D(2)O plays a stabilizing role on strands separation during thermal denaturation of DNA.

U.V. induced enhancement of recombination among lambda bacteriophages: relation with replication of irradiated DNA.
Experimental results are reported showing the dependence of the U.V. induced enhancement of recombinants on the presence of the functional O gene product. This fact is tentatively interpreted as a replication dependence of the U.V. induced recombination.

Repair of U.V. damages in Bacillus subtilis cultures competent for transformation: difference between competent and non-competent fractions.
The repair of U.V. damages to DNA in B. subtilis cultures competent for genetic transformation has been studied. The comparison of survival curves for competent and non competent fractions shows that: i) excision repair is more effective in competent than in non competent bacteria; ii) recombination repair is more effective in non competent than in competent bacteria. These facts support the hypothesis that metabolic conditions and, very likely, DNA replication play a role in the regulation of the efficiency of the two different mechanisms of repair.
