[Electron microscopic analysis of the individual genes of the influenza virus]

The lengths of fragments of influenza virus strain A/USSR/90/77 (H1N1) genome RNA separated by electrophoresis and treatment with 0.25 M glyoxal solution were measured. The number of nucleotides of these fragments was estimated in regard to marker ribosomal 16 S and 23 S E. coli RNA. The results were compared with analogous data obtained by other methods.
