Viruses

A tiny, nonliving particle that invades and then reproduces inside a living cell.

the study of viruses and viral diseases

Living cell in which a virus can actively multiply or in which a virus can hide until activated by environmental stimuli

Helps inject the DNA

A type of viral (phage) replication cycle resulting in the release of new phages by lysis (and death) of the host cell.

A phage replication cycle in which the viral genome becomes incorporated into the bacterial host chromosome as a prophage and does not kill the host.

This occurs when the virus attaches to its host. This is the moment in which the virus recognizes the host as a cell to infect and will inject viral DNA or RNA into the host.

Viral genetic material enters host cell

Parts of the virus are made.

When a viral infected cell bursts and releases large amounts of organic matter.

A process that takes place after separation of the viral infectious particle from host cell by budding or sealing of spherical capsid.

The viral DNA hides in the host DNA and replicates with the host in stealth.

A condition in the host cell causes the viral DNA to activate into the lytic cycle. This can be caused by hormones or physical factors.

A viral infection causing small painful blisters and inflammation, most commonly at the junction of skin and mucous membrane in the mouth or nose or in the genitals.

A virus that attacks and destroys the human immune system.

Human Papillomavirus

A virus that infects bacteria
