Cards

Term
Components of viruses
Definition
- Nucleic acids (DNA or RNA)
- Protein coat
- Sometimes a membranous envelope
Term
Capsid
Definition
A protein shell that encloses the viral genome
Term
Envelope
Definition
Membrane that surrounds the capsid; help them infect the host cells
Term
Capsomeres
Definition
Protein subunits that build capsids
Term
Virion
Definition
One viral particle
Term
Prophage
Definition
Viral genome that is inserted into bacterial genome
Term
Reverse transcriptase
Definition
In retroviruses, it uses an RNA template to make DNA
Term
Provirus
Definition
The viral DNA that is integrated into the host genome
Term
5 ways viruses are transmitted
Definition
- Airborne (cold, flu)
- Mucus membrane
- Bloodborne
- Vectorborne
- Placental transmission
Term
Transposons
Definition
Small sections of genome that can jump around. They are found in eukaryotic cells
Term
Vaccine
Definition
Something that causes our bodies to create antibodies. It is only used for prevention. It can be a dead form of the virus or a disease that is less viral
Term
Emerging viruses
Definition
A disease that suddenly becomes apparent
Term
Epidemic
Definition
A virus outbreak that is on a relatively small scale. It is somewhat localized
Term
Pandemic
Definition
Worldwide virus
Term
Prions
Definition
slow acting, virtually indestructible infectious proteins that cause brain disease in mammals
Term
Viroids
Definition
Small circular RNA molecules that infect plants and disrupt their growth
