module 2

Question 1

compartmentalization of the cell interior is advantageous to eukaryotic cells

Answer 1

Eukaryotic cells have an organized cytoskeleton
Compartmentalization allows for discrete areas within the eukaryotic cell for specialized processes

Question 2

components of a virion

Answer 2

Virion- a complete/ mature virus particle, it is the form of the virus that can exist outside the cell and infect new cells

Question 3

Prions

Answer 3

interacting with particles of the same protein in altered conformation

Question 4

Satellite nucleic acids

Answer 4

Also nucleic acids that need helper virus for replication
The difference is that they don’t encode capsid proteins

Question 5

how oncoviruses cause cancer

Answer 5

cause cancer by inducing uncontrolled cell growth

1. viral DNA integrates into host genome, disrupting genes
2. viral proteins directly stimulate cell (rapid increase in numbers)
3. long term infection causes inflammation, leading to DNA damage
4. some viruses evade immune protections, allowing prolonged infection and mutation accumulation
