|
Bacteriophage |
A virus that infects bacteria |
|
|
Acellular |
Lack components of cells (Ex. Viruses) |
|
|
Lytic Cycle |
Creates new viruses -Copying of viral DNA -Transcription+Translation of viral DNA -Bacterium bursts and spreads virus |
|
|
Lisogenic Cycle |
DNA of virus combines with DNA of bacteria - Remains there until something causes start of infection |
|
|
Endocytosis |
Cell membrane envelopes virus |
|
|
Animal Viruses... |
1.Endocytosis 2. Capsid creates channel through host cell membrane and injects genome 3. Fusion of envelopes, genome enters host cell |
|
|
Reverse Transctiptase |
RNA to DNA |
|
|
Plant Viruses... |
Do to cell wall, cell must be damaged for virus to enter (Horizontal Transmission) or Plant gets virus from parent (Vertical Transmission) |
|
|
Horizontal Transmission |
Virus transferred between members of the same generation |
|
|
Vertical Transmission |
Virus is transferred from mother to child |
|
|
Vaccines are made from... |
-Weakening live viruses - Dead viruses -Molecular subunits of viruses |
|
|
Fusion Inhibitors |
Keep HIV envelope from merging with host cell membrane (Also use protease+integrase inhibitors) |
|
|
Prion |
Form of protein that causes degenerative diseases in the nervous system |
|
|
Viroid |
Strand of RNA that causes disease in plants |
