Concept explainers

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.

Question

Some viral detection techniques involve a serological assay. This assay looks for the presence of

antibodies to virus proteins.

virus particles under a microscope.

viral nucleic acids.

host cells that have undergone lysis.
