[Chemical and physico-chemical properties of the DNA of Newcastle group bacteriophages].

DNA of H-1, H-5, H-10, H-17, and H-22 phages were studied, their nucleotide composition, their buoyant densities in cesium chloride and cesium sulphate, curves of melting and spectra of circular dichroism were determined 5-oxymethylcytosine in the composition of H-I and H-22 phage DNA was shown immunologically to be glucozylated.

[Physicochemical properties of the Newcastle group bacteriophages].

Physico-chemical properties of dysentery therapeutic-prophylactic Newcastle phages H-I, H-5, H-10, H-22 were studied. The morphology of the phage particles is described; their molecular weight and buoyant density in CsCl were determined by ultracentrifugation. The type of nucleic acids (DNA) was determined.

[Physical characteristics of simian adenovirus SA7].

Physical characteristics of simian adenovirus SA7 virion were studied. The buoyant density of SA7 virions was found to be 1.356 g/cm3.

[GC-pair distribution in the DNA of simian SA7 and human type 6 adenoviruses].

The buoyant density values in cesium chloride of DNA fragments of simian adenovirus SA7 obtained with restricting endonucleases of R. EcoRI, R. BamHI, R.

[Physicochemical characteristics of the Penicillium-bacterial virus type 5 and its nucleic acid].

Physico-chemical characteristics of PBV-5 virus and its nucleic acid were studied. Morphologically, the virus is a rectilinear polyhedron 270 A in diameter, without a process. The sedimentation constant of a virus particle is 117S, the buoyant density of the virus in cesium chloride density is 1.
