<h3>Process of viral infection.</h3>
A virus is a microorganism that has the ability to reproduce only by infecting a living host.
The main features of a virus include:
- nucleic acid genome ( RNA or DNA)
For a virus to be able to cause an infection,it has to pass through the following steps:
- Attachment of the virus to the host cell.
- Entry of the viral genetic material into the host cell
- Genome replication and gene expression: through the ribosomes of the host cells, enzymes are released which are used to replicate the invading virus to produce new ones.
Therefore, the enzymes that are used to replicate a virus are synthesized by the host cell.
