Explain Influenza virus and what it is made up of.
Influenza viruses are enveloped, single stranded RNA viruses

3 species
Explain "Minus Strand"
*eight single stranded "minus strand" RNA molecules

The RNA does not directly code for proteins......instead a complementary RNA "the plus strand" is synthesized from the minus strand
Hemagglutinin is HA
the protein a virus uses to bind to a host cell
Neuraminidase
cleaves NANA from glyco proteins which enable the virus to ecape from the cell
NANA
Binding to NANA causes the virsl envelope to fuse with the cell membrane leading to endocytosis.
