Definition
| most commonly used system of virus classification by David Biltmore ex. dsDNA, ssDNA |
|
|
Term
|
Definition
| mRNA in transcribed directly from DNA ex. herpesvirus |
|
|
Term
|
Definition
| DNA is converted to double stranded form before RNA is transcribed ex. parvovirus |
|
|
Term
|
Definition
| mRNA is transcribed from the RNA genome ex. rotavirus |
|
|
Term
|
Definition
| genome functions as mRNA ex. picornavirus |
|
|
Term
|
Definition
| mRNA is transcribed from the RNA genome ex. rabies (rhabdovirus) |
|
|
Term
| ssRNA with reverse transcriptase |
|
Definition
| reverse transcriptase makes DNA from the RNA genome, DNA is incorporated into host, mRNA is transcribed from incorporated DNA ex. HIV |
|
|
Term
| dsDNA with reverse transcriptase |
|
Definition
| double stranded DNA, but viral DNA is replicated through and RNA intermediate ex. hepatitis B virus |
|
|
Term
|
Definition
| viruses that introduce genes that cause uncontrolled growth of cells called oncogenes and interfere with expression of genes that control cell division ex. HPV -> cervical cancer |
|
|
Term
|
Definition
| causes the highly infectious airborne disease; contains 8 segments of RNA surrounded by an envelope and external antigen receptors |
|
|
Term
|
Definition
| glycoprotein on surface of influenza - 17 variations; helps virus attach to silica acid to facilitate entry into host cell |
|
|
Term
|
Definition
| glycoprotein on surface of influenza A - 10 variations; helps the viral progenies excise from human cell and exit the host cell |
|
|
Term
|
Definition
| extremely infectious virus due to transmissible antigens |
|
|
Term
|
Definition
| produced by white blood cells to fight virus and increases temperature |
|
|
Term
|
Definition
| happens when mutations take place in genes encoding for HA and NA antigens diminishing host immunity to a virus - reason why new vaccines are needed yearly |
|
|
Term
|
Definition
| happens when an organism is infected with two viruses at the same time resulting in a mixing of genes called gene reassortment; H1N1 happened due to this |
|
|
Term
|
Definition
| single strand circular RNA molecules that mostly infects plants and range in size 250-400 nucleotides ex, potato spindle tuber |
|
|
Term
|
Definition
| lack DNA and RNA and consists primarily of proteins, spreads due to consuming meat from your own species |
|
