6. TYPES Virus are not named by the Linnaean classification system.
Instead, the nucleid acid type and their expression type are used.
They are give families and orders, but these do not represent phylogenies.

9. VIRAL INFECTION PATHWAY

10. The viral DNA forms a circle.
The viral DNA forms a prophage by combining with the host´s cells DNA.
The viral DNA directs the host cell to produce new viral parts that assemble into new bacteriophages.
The prophage replicates along with the host cell´s DNA.
The host bacterium breaks apart and bacteriophages are able to infect new host cells.
Many cell divisions produce a colony of cells infected with the virus.
The prophage may leave the host´s DNA and enter the lytic cycle or may continue to incubate in the host´s cell.
The virus destroys the host cell.
