Comparative characterization on the segmented RNA structure of influenza viruses A/Singapore 1/57 and A/Hong Kong 1/68.

A comparative characterization of the segmented RNA structure of A/Singapore 1/57 and A/Hong Kong 1/68 influenza viruses was done by polyacrylamide gel electrophoresis. The genomes of the viruses studied consist of 6 segment classes, with a total molecular weight of approximately 4 million daltons. The mathematical method suggested allows to define the number of RNA fragments, which is equal to 8-9, with a total molecular weight of about 6 million daltons. Electrophoretic patterns of the viruses investigated have individual features.
