CYCLONE SMACKDOWN LETS GET READY TO RUMBLE QUESTION

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.

QUESTION #2 • What is uncoating? • When a virus fuses to a host cell, allowing the capsid into the cell.

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.

BONUS! May the fastest team win

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!

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

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.
