||"With the advent of improved electrophoretic techniques for separating nucleic
acids and proteins, it was demonstrated that the influenza A genome consists of
eight separate RNA segments (primary sources)"
||"Influenza A viruses are lipid-enveloped viruses containing a genome composed
of eight strands of negative-sense RNA that encode ten viral proteins. These gene
segments are encapsidated in a virally encoded nucleoprotein (NP), and the ribonucleoprotein (RNP) structures are associated with the three subunits of the viral polymerase (PB1, PB2, and PA)."
