2 mandatory components of a virus
What is a protective capsid made of protein.
Genetic material(DNA or RNA).
The difference between an epidemic and a pandemic
Epidemic-confined to a specific geological region.
Pandemic-widespread / global.
Viruses are alive
What is no?

Curly shape of virus, correct name
Tobacco Mosaic Virus
1 mild and 1 severe disease caused by a virus
Mild - common cold, chicken pox
Severe - AIDS, cholera
2 reasons as to why viruses are not living
- No not metabolize energy
- Cannot grow
- Do not perform cellular respiration
- Cannot reproduce on their own
Mandatory component for virus to reproduce.
Host
How does Covid get transmitted?
Contact, Droplets, and Objects.
Shape of HIV
What is spherical
One example of an illness that goes through a change and turns into a different illness while still being the same virus
What is Chicken pox -> Shingles
(varicella zoster virus)
How big are viruses?
Less than 100 μm(Micrometers)
At what point do the Lytic and Lysogenic cycle separate?
After the virus attaches to the bacteria.
What is it called when a bacteria infected with viruses bursts.
Lyse/Lysing
The 4 types of shapes. Not names.
What are Helical, Polyhedral, Spherical, Complex
Full name for HPV
What is Human Papillomavirus
Organelle that a virus lacks. Exact answer, in our notes.
What is Cytoplasm
Describe each step of the Lysogenic Cycle
1. Virus attaches to the bacteria
2. Virus transfers it's DNA(genetic material) into the bacteria
3. Bacteria replicates both its self and the Virus
4. New bacteria is produced with virus DNA integrated.
An example of unusual virus exposure we talked about in class
What are Chicken Pox Parties?
5 parts of the bacteriophage
What are Head, tail, sheath, viral DNA, and capsid.
3 reasons as to why you can't get rid of the herpes simplex virus once you get it.
- It has a period of dormancy
- Stress causes it to become active
- It replicates and destroys other cells
The 4 viruses that we looked over
- Tobacco mosaic virus
- Adenovirus
- HIV
- Bacteriophage
Describe each step of the Lytic Cycle
1. Virus attaches to the bacteria
2. Virus transfers it's DNA(genetic material) into the bacteria
3. Virus's DNA is incorporated into host's DNA creating more virus DNA
4. Virus components connect and lyse(break) the cell
5. New viruses are created
What does vaccination do?
How does it work?
Vaccines teach the immune system how to recognize and fight off specific disease-causing germs
