Reproduction
When a virus infects a bacterium, viral nucleic acid injects this into the cell.
Viral nucleic acid/Virus' genetic material
Example of adenovirus
Common cold
Viruses can only replicate inside of this.
Host cell
If a person has HIV, but does not show the symptoms, then the virus is in this stage.
Lysogenic cycle
Example of retrovirus
HIV
This is the type of medicine that is the most effective way in preventing the spread of a virus.
Vaccination
This cycle destroys the host cell.
Lytic cycle
Example of prion
Scrapie, BSE, CJD
This is a virus that attacks bacteria.
Bacteriophage
During the lysogentic cycle, the provirus does this.
Inserts itself into cell & viral DNA is replicated.
Example of cancer causing virus
HPV; EBV
Two macromolecules that make up a virus
Protein and nucleic acid
