Viral Replication

It is the process in which a virus enters the susceptible host cell and induces a living host cell to synthesize the essential components for the synthesis of new viral particles. The particles are then assembled and the newly formed virions escape from the cell to infect other cells.

Virus particle (Virus)

Viruses are the smallest known infectious agents. They are all built up of nucleic acid and protein coat(s) and some may have an outer lipoprotein envelope. They replicate in cells and may thereby lead directly to cell damage and cause disease.
These are ultramicroscopic particles containing nucleic acid surrounded by protein, and in some cases, other macromolecular components such as a membrane like envelope.
