title: [Structural characteristics of DNA of Bacillus thuringiensis phages].
abstract: The spectral characteristics of DNA from two phages of the polylysogenic Bacillus thuringiensis subsp. galleriae culture 1-97 were studied. The typical parameters of melting and the negative reaction with formaldehyde are indicative of the double-helical structure of these DNAs. The phage DNAs differ in the molar content of nitrogen bases (32 and 38 mole% of GC) and in their distribution along the molecule. This distribution is uniform in the DNA of one phage whereas the other phage DNA is composed of heterological segments with a different nucleotide composition.
