|
An exit method used by viruses which does not immediately destroy the host bacteria |
Extrusion |
|
|
What part of the E.coli T4 phage attaches to the host cell receptors |
Protein fibers at the end of the tail |
|
|
During attachment of phage to E.coli the phage |
Attaches to proteins or carbohydrates on the bacteria surface |
|
|
Viruses that infect bacteria are referred to as |
Bactriophages |
|
|
The correct order for the stages of phage infection |
Attachment, genome entry, synthesis, assembly, release |
|
|
Which of the following are ways in which animals viruses can be classied |
Route of transmission, presence of envelope, genomic structure, viruses particle strucures |
|
|
Key feature of all viral infections is the |
Separation of viral nucleic acid from the capsid |
|
|
What is only made of infectious proteins |
Prions |
|
|
A latent infection, the virons are |
An infection in which the virus can not be detected until reactivation |
|
|
Capsid and nucleic acid combined are called |
Nucleocapsid |
|
|
Ways a virus can be transmitted |
Enteric, respitory, zootonic, and sexually transmitted |
|
|
Why are viruses not alive |
Use host machinary to support reproduction, are extracellular inert |
|
|
Viruses that are are segmented means that have |
More than 1 nucleic acid |
|
|
What stage in production of infection is the virus multipling in a cell but does lyse cell |
Temperate phage |
|
|
What state that a bacteria carrying phage called when there is no sign of infection |
Lysogen |
|
|
A lamda Intergrated phage is called |
Prophage |
|
|
A viral envelope closely resembles the |
Plasma membrane |
|
|
Shapes of viruses |
Icosahdral, complex, helical |
|
|
Prions are |
protenaceous infectious particles |
|
|
An example of a latent infection |
Herpes simplex 1 |
|
|
Bactiophages like T4 and animal viruses differ because |
bacteriophages leave a capsid, while a animal viruses entry involves the entry of the whole nucleocapsid |
|
|
An infection in which the virus is continually present is referred to as |
Persistent |
|
|
What part of the attached bacteriophages enters through the host cell |
Nucleic acid |
|
|
General transduction is |
Involves random transmission of any gene of donor cell is transferred |
|
|
Specialized transduction |
Only genes adjacent to Intergrated phage DNA can be transferred |
|
|
Viron is composed of |
Protein and either RNA or DNA |
|
|
The nucleocapsid is composed of |
RNA or DNA |
|
|
Sexually transmitted virus disease |
HIV |
|
|
Zootonic transmitted viral disease |
Rabies, airoviruses (anthropods) |
|
|
Respiratory transmitted viral disease |
Influenza |
