Cyclone smackdown! Let’s get ready to rumble!

Question #1 What is transmission? Give an example of this.
Viruses moving between host cells. This can be seen in mosquitos.
3
Question #2 What is uncoating?
When a virus fuses to a host cell, allowing the capsid into the cell.
4
Question #3 What is the difference between lytic and lysogenic reproductive cycles? Lytic reproduction allows viruses to use their host to replicate, and then destroy the host. Lysogenic gets incorporated into the host’s DNA.
5
BONUS! May the fastest team win
6
For 2 extra points, answer this question!
In the lysogenic reproductive phase, once the virus is incorporated into the host’s DNA, the virus is considered a what? Provirus!
7
Question #4 What does the regressive hypothesis state?
Viruses came about from smaller cells that were parasitic on larger cells. They became dependent on a host
8
Question #5 What does the progressive hypothesis state?
Viruses came from jumping genes, called transposons.

Question #6 What is the “virus first” hypothesis?
Viruses were early “organisms” that helped develop life. Like the ancestors of first life forms

Question #7 What is the difference between satellites and viroids?
Satellites depend on a helper virus to infect a host cell, they also need them to reproduce. They are super codependent…like a clingy girlfriend. Viroids are circular strands of DNA and do not need help reproducing. These are the miss independent of the group

Question #8 What are prions? How can they affect an entire organism so quickly? They are proteins that fold incorrectly. They can cause incorrect folding in other proteins. Incorrect shape, or folding, can cause failure of certain functions.
