Term
| When does a viral infection begins? |
|
Definition
When a virus absorbs to a specific chemical site on the host. The nucleic acid of the virus then penetrates into the cell (normally would inject through the tail)
Once inside the cell:
a.lysogenic infection
b.lytic infection |
|
|
Term
|
Definition
| the virus commandeers the cell's reproductive machinery and begins reproducing new virues |
|
|
Term
|
Definition
| A period from infection to lysis |
|
|
Term
|
Definition
| A virus following a lytic cycle |
|
|
Term
|
Definition
| occurs once lytic stage burst. DNA is reverse-transcribed from RNA and then incorporated into the host cell genome |
|

Term
|
Definition
| A virus in a lysogenic cycle |
|
|
Term
Types of viruses:
Plus-strand RNA
Minus-strand RNA
double-stranded RNA viruses
singel/double-stranded DNA viruses |
|
Definition
Plus-strand RNA:common cold; indicates that proteins can be directly translated from the RNA includes retroviruses (AIDs)
Minus-strand RNA: measles, rabies, flu; complement to mRNA and must be transcribed to plus-RNA before being translated |

|
Term
| Denfense against viral infection |
|
Definition
antibodies bind to a viral protein, and with cytotoxins T cells, which destroy infected cells
spike proteins are recognized by human antibodies when fighting
when spike proteins change, the antibodies fail to recognize them, and the virus may avoid detection until new antibodies form. |
