Solution
Virus:
Viruses are intracellular parasites.
To produce a progeny virus, viruses must obtain access to target cells and take over the host cellular machinery.
The "virus life cycle" refers to the several processes required in virus propagation that occur inside cells.
Stages in the virus life cycle:
The life cycle of a virus is separated into three stages: entry, genome replication, and exit.
In the viral life cycle, the initial phase of infection occurs when the virus comes into contact with the host cell and inserts viral material into the cell.
Attachment occurs when a viral particle finds the host cell and adheres to the cell surface; penetration occurs when a virus particle enters the cytoplasm, and uncoating occurs when the virus sheds its capsid.
The naked viral genome is used for gene expression and viral genome replication after it has been uncoated.
Finally, after the viral proteins and genomes have accumulated, they are organized into a progeny virion particle and discharged extracellularly.
