What biological molecules are present in flu virus?

The influenza virus primarily consists of proteins, lipids, and nucleic acids. Its outer structure is made up of a lipid bilayer derived from the host cell membrane, containing viral proteins such as hemagglutinin and neuraminidase. Inside, the virus contains RNA as its genetic material, specifically segmented negative-sense single-stranded RNA. Additionally, the virus has associated proteins that play roles in replication and assembly.
