Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.
The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.
The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.
