Definition
| 5 stages of viral replication cycle |
|
|
Term
|
Definition
| Eclipse and maturation stages of virus |
|
|
Term
|
Definition
infectious particles are removed from the environment through attachment to host cells, thus can no longer infect other cells
Viral nucleic acid or vision enter the host cell and replication of proteins and viral nucleic acid begins |
|
|
Term
|
Definition
| virus nucleic acids and proteins are assembled into visions inside the host cell so no detection of newly created visions in the medium yet |
|
|
Term
|
Definition
number of visions released
varies with particular viruses and their host cells from few to 1000s |
|
|
Term
|
Definition
the process in which the vision loses its outer coat and the viral genome is exposed
can occur inside or outside of the cell |
|
|
Term
eukaryotes: immune system, RNAi
prokaryotes: CRISPR and endonucleases |
|
Definition
| How do cells protect against viruses? |
|
|
Term
David Baltimore Classification System
based on relationship of viral genome to mRNa |
|
Definition
|
|
Term
| positive-strand RNA viruses |
|
Definition
| single-stranded RNA genome with the same orientation as its mRNA |
|
|
Term
| negative-strand RNA viruses |
|
Definition
| single-stranded RNA genome with orientation complementary to its mRNA |
|
|
Term
|
Definition
animal viruses responsible for causing certain types of cancers and acquired immunodeficiency syndrome (AIDS)
have ssRNA in visions but replicate through dsDNA intermediate |
|
|
Term
|
Definition
| process of copying the information stored in RNA into DNA via a hybrid RNA-DNA intermediate |
|
|
Term
|
Definition
| enzyme that copies RNA into DNA |
|
|
Term
|
Definition
| needed for replication of viral nucleic acid so synthesized soon after infection |
|
|
Term
|
Definition
| proteins found in the viral coat, structural proteins, etc. synthesized later after infection |
|
