Viruses
|
- Replication is directed by viral nucleic acid in host cell
- Never possess both RNA & DNA - Viruses don't possess the enzymes needed to produce energy, they have to rely on the protein production machinery of the host cell. |
|
|
Lysogenic Cycle
|
- viral genetic material remains latent
- transferred to each individual daughter cell as host cell divides. |
|
|
Lytic Cycle
|
Genetic material of the virus divides and takes over the metabolic machinery of the host cell and begins producing virions.
|
|
|
Interferons
|
Glycoproteins that interrupt replication of both RNA & DNA viruses.
|
|
