Viruses to Cells
By: Julie Kim
- Attach/Enter cell
- Virus DNA incorporated into host cell DNA
- Cell divides and each new daughter cell has viral DNA
- The virus becomes active and enters Lytic cycle
Characteristics of life
- Have metabolism or respiration
- Cellular structure
- Maintain homeostasis
- Have DNA or RNA
1. Describe the typical structure of a virus. What is a virus made of? What biomolecules
would you find in a virus?
Viruses have a protein cost called capsid, DNA or RNA, some enzyme and some have lipid membrane
2. Discus different ways virus enters cell
They can attach to the membrane and injects DNA/RNA , virus and envelope fuse allowing virus to enter cell
3. Explain why the Ebola virus would not infect a tobacco plant.
Tobacco plants have antibodies that would be immune in a way to the Ebola virus
4.Name five viruses and the type of cell that they attack.
Ebola - liver cells
HIV- T cells
Rabies - blood cells
Influenza- epithelial cells
Swine flu- epithelial cells
5. You have been diagnosed with the flu. Explain why a doctor will not provide you
with a prescription for antibiotics in order to cure infection.
Antibiotics won't work because the virus isn't living to begin with, you can kill something that isn't alive.
Instead they can give a vaccine to prevent or weaken the virus
6. How is it that a person can be infected with a virus such as HIV and not exhibit
It isn't a virus that affects right away so it may take some time because of the virus itself
