Viruses are made of one or more nuclei acid molecules surrounded by a coat protein or capsid. So the core of the virus will contain the viral genome. Some viruses' capsid maybe enclosed with an envelope derived from the host cell (the cell that the virus is infecting), and this envelope is also derived from the host cell membrane.

In redox reaction, the one element gains oxygen or loss hydrogen molecule. The other element losses oxygen or gain hydrogen in the reaction reaction.  One molecule gets oxidize while the other molecule may get reduced in the redox reaction.
