Caption:
This illustration depicted a 3D computer-generated rendering of a half-sliced influenza (flu) virus with a grey surface membrane, set against a white background. The virus’ surface proteins, hemagglutinin (HA) and neuraminidase (NA), were highlighted in light and dark blue, respectively. Inside the virus, its ribonucleoproteins (RNPs) were shown, with their coiled structures, and three-bulbed polymerase complex on the ends. An influenza virus’ RNP is composed of both RNA and protein. Every influenza virus has eight RNP segments that correspond to the virus’ eight total gene segments. Three of these RNP segments encode the virus’ surface proteins, i.e., the HA, NA and M proteins.
