September 24th - Viruses

Well, today we reviewed the structure of the cell before moving on to the process of viral replication. In doing this, we saw the two type of viral cycles: the lytic cycle and the lysogenic cycle. Please know the differences and what happens in each of them. (The lytic cycle is the one that results in new viruses and the lysogenic cycle is the one that results in continuous infection of new generations of host cells without new viruses being produced.) The lysogentic cycle can lead into the lytic cycle. We also spoke a little about the second layer - the membrane envelope - that can form around some viruses. I gave you a worksheet to do on viruses.

Homework: Finish virus worksheet, and the viral replication worksheet. I also handed out the Virus Project worksheet today. Take a look at this and begin working on it as soon as you can.
