What Function Does the Neuraminidase Protein of Influenza Virus Carry

Question

What function does the neuraminidase protein of influenza virus carry out?
A) It binds to sialic acid and helps the virus enter the host cell.
B) It helps release virions from virus producing cells.
C) It is involved in the glycosylation process of the NA protein.
D) It cleaves the HA protein into two functional domains.
E) It helps the virus evade the immune system.

Accepted Answer

The neuraminidase protein helps release virions from virus producing cells by cleaving sialic acid residues on the surface of infected cells, allowing newly made virus particles to exit and infect other cells.
