Physicochemical characteristics of cyanophages and their components

: The paper presents the results of the study on the physicochemical properties of DNA, polypeptide composition of proteins, as well as features of quaternary structure of virions of cyanophages LPP-IA, LPP-3, LPP-3A, A-1, A-2, and N-2 lysing filamentous and heterocyst cyanobacteria. Such characteristics may be used as hierarchially important signs in compiling the classificational scheme of cyanophages.
