[Effect of liver chromatin DNAse on closed circular DNA of PM-2 phage and simian virus 40].
Comparative effect of the DNAse from rat liver chromatin and Neurospora crassa endonuclease S1 on closed circular superhelical DNA of PM-2 phage and Simian Virus 40 is studied. It is shown that both of them--the DNAse from chromatin proteins and endonuclease S1--are specific to single-stranded regions in DNA molecular. It is suggested that chromatin protein DNAse participates in reparation processes.
