What does a virus consist of?
DNA/RAN surrounded by a protien coat
What are the shapes of viruses?
Isometric - equal sides
Helical - kind of rod shaped
Complex - Stop sign with legs
What is the lytic cycle?
When a virus is "alive."
: When you have a cold sore.
What is the latent cycle?
When the virus is inert or dormant.
: when you don't have a cold sore.
What are the 6 steps of the lytic cycle?
Assembly (or maturation)
What happens during attachment?
The virus attaches to the bacteria
What happens during penetration?
The virus or its nucleic acid enters the cell.
What happens during Transcription/Replication?
Duplication of viral components
What happens during assembly?
Replicated viral components become a mature virus
What happens during release?
Host cell bursts and releases virus's to the environment
What is masking?
When a virus uses part of the old cells membrane as its envelope, in order to look like the host cell.
What is Lysogeny?
Replication of a temperate virus
What is incorporation?
When the DNA/RNA of the virus incorporates into the host chromosome
DNA only replicates when the host replicates
What is lysogenic conversion?
When the virus confers new properties on to the cell
