Virus Flashcards
What is a virion?
Outside the host cell, the virus particle. They are metabolically inert
What is viral replication?
Multiplication of virion
What are the four steps for viral replication?
- Attachment
- Penetration
- Replication
- Synthesis
- Assembly
- Release
What is budding?
when the enveloped virus moves towards the cell membrane and forces themselves through the cell membrane
Lytic Cycle
The replication process where the host cells die
Lysogenic Cycle
Virus remains active for long period without replicating in the host cell (HIV uses this)
What are the two types of vaccines?
Inactivated virus and attenuated virus
What is attenuated virus?
Live virus that is reduced by multiple passaging the virus into cells that are not a natural host for that virus
What is inactivated virus?
dead virus, killed using chemical agents
What are two DNA viruses?
Chickenpox and Smallpox
