BRAINCAKEThe Replication of Viruses
Viruses can only replicate by using the host cell apparatus as they are non-living.
A virus consists of DNA or RNA enclosed in a protein coat or capsid.
Viruses attach to the host cell using attachment proteins or glycoproteins on their surface and inject their RNA or DNA into the host cell.
