Influenza A Virus Replication
Process by which a virus enters a host cell and infects it by reproducing
its own genetic material and assembling into virus particles.
The influenza virus is a class of viruses
containing RNA as its hereditary material.
It replicates by entering a host cell and using this cell's resources to
produce hundreds of copies of the viral RNA.
The virus attaches to the outside of the host cell and its RNA enters
into the cell. The viral genes are transcribed and translated by the cell's
enzymes and ribosomes. In this way, the virus takes over the cell's productivity.
Now, instead of producing only new cellular material, the cell produces
hundreds of new virus particles. The new virus particles are eventually
released from the cell and drift off, and some may land on a host cell of
their own to pirate.
