1. HAPPY WEDNESDAY Bellwork Bellwork: Draw and Label the viruses above using the following terms: Capsid, DNA/RNA, Envelope.

2. Happy Tuesday Bellwork Draw and Label the viruses above using the following terms: Capsid, DNA/RNA, Envelope. CAPSID DNA RNA CAPSID RNA ENVELOPE

3. Virus and Microorganisms Notecards 4 th and 5 th Period Due Wednesday (2/18/15) Antibiotic AZT Capsid Host Human Immunodeficiency Virus (HIV) Immunization Influenza Lysogenic Cycle Lytic Cycle Lysis Microorganism Parasite Pathogen Retrovirus Vaccine Virus

4. Essential Question: How does a virus reproduce? Standard: describe viral reproduction (B4C)

5. Virus HW Quiz On a sheet of paper, answer two out of the three questions. Must be in your own words. Each question must be answered in 1 paragraph (5-7 sentences OR half a page). 1.Why are viruses not living organisms? 2. What is a virus? 3. How do viruses harm us?

6. Page 58: Virus Reproduction Notes

7. H. Viral Reproduction 1. Once viral genes are inside the host cell, two processes may occur: the lytic cycle or the lysogenic cycle.

8. Lytic Cycle

9. Lytic Cycle (BANG BANG!) 1. The Virus attaches to the outside of the cell. 2. Viral genes are inserted into a host cell. 3. Virus parts are made/replicated. 4. Virus parts are assembled. 5. The host cell bursts/lysis and is destroyed 6. New viruses infect new host cells.

10. Lytic Cycle - Viruses

11. Create an analogy……… Partner 4: The Lytic Cycle is like a ___________ because ___________. Partner 3: I agree OR disagree because ______________________.

12. Lysogenic Cycle Hidden viruses “hide” for a while inside host cells before becoming active Steps to the Lysogenic Cycle: 1.Attach to cell 2.Inject DNA/RNA 3.Integrate/Join DNA/RNA into cell 4.Wait 5.Remove DNA/RNA 6.Become active (lytic cycle)

13. Lysogenic Cycle - Viruses

14. Create an analogy……… Partner 3: The Lysogenic Cycle is like a ___________ because __________. Partner 4: I agree OR disagree because ______________________.

15. DRAW THIS!!!

16. Sage and Scribe: Cycle Steps Get into partners—decide who is partner A and who is partner B. – Partner A: Describe the steps for the Lytic cycle. – Partner B: Draw each step. After a few minutes, we will switch to the Lysogenic Cycle and you will switch roles.
