Is a virus a living thing?Structure of an influenza virus:

http://micro.magnet.fsu.edu/cells/viruses/influenzavirus.html

A virus attaches to a cell. The shape of the proteins on the

outside of a virus matches the shape of proteins on a cell in the same way that puzzle pieces fit

together. This tricks the cell into letting the virus pass through its

membrane.

Then, the virus releases its RNA into the cell. The cell does not

know that this RNA is not its own. It copies the virus’ RNA and new

viruses form inside the cell. Then, the new viruses break out of the cell and go on to attach to other

cells.

The influenza virus mutates (changes) easily. Therefore, the

antibodies that your immune system produced last year to

destroy influenza viruses may not be effective against this year’s

influenza viruses.
