Viral Replication

Viruses are Intracellular obligate parasites that they cannot replicate their genes without the help of a living cell. Certain proteins on the virus particle must fit particular receptor sites on the particular host cell surface. Host cell provides the energy & system for the synthesis of viral proteins & nucleic acids. The cell membrane of the host cell infolds the virus particle, enclosing it in a pinocytotic vacoule. Most DNA viruses assemble in the nucleus while most RNA viruses develop only in cytoplasm.
