T4 Tuesday

Agenda:

1. Take out UP 6-9 w/ stamp sheet
2. Star/wish

3. Go over lab (6-9)
4. Notes- viruses
5. Video: Viruses

Today in class, the first thing we did was we took out our homework so that Mrs. Stein could check to make sure we completed the lab, 6-9.

Next we gave our star and our wish to our last scribe, Aleko.

Next we went over our lab from yesterday, UP 6-9. In "Whom Infected Whom?" The lab groups were all teams of epidemiologists and had to find out who first got the disease and who spread it to others. In most groups, Mr. Paek was the one who had the disease in the first case. Then it got to Ed, who showed no symptoms but infected others. S, Ed was the carrier of the disease.

Then, we took notes on viruses. Lets remember that there are three different kinds of viruses.

-This is a bacteriophage.

This is a tobacco mosaic virus-

-And this is an influenza virus. Which is similar to HIV

This picture is a picture of the lysogenic cycle. In this cycle, the viruses DNA attacks the prokaryotic cells chromosomes. When they split, they have made two virus infected cells.

-This is the cycle of the lytic cycle. Where a bacteriophage lands on a prokaryotic cell and uses its DNA to copy itself.

We also talked about viral diseases. We talked about how viruses attack and destroy cells and how it disrupts homeostasis. And then we talked about common viral diseases: influenza, the cold, HIV, chicken or small pox, warts, and the West Nile.

Finally we finished class with the video on viruses. This went over what we talked about in class a little more in depth.
