Virus Structure, Classification, and Cycles of Infection 

2. Overview 1. Virus and Virus Structures 2. Adenovirus 3. Retrovirus
4. Lytic Cycle
5. Lysogenic Cycle
6. ABC's

3. What is a Virus?
an effective agent that duplicates its self- inside living cells
Can infect all life forms
Particles are made of proteins and nucleic acids
Non- living
Max DeAngelo

4. Virus Structure Capsid : Protein shell of the virusz
Virus Structure
Capsid : Protein shell of the virus
Genetic information
Max DeAngelo

5. Viruses Structures: T4 Bacteriophagez
Viruses Structures: T4 Bacteriophage
Made of a Tail sheath and Tail fibers
Contains DNA in the head
Infects Bacteria in order to spread
Max DeAngelo

6. Symptoms of a Bacteriophage
Fever
Chills
Diarrhea
vomiting
Max DeAngelo

7. Andenovirus Andenovirus affect mostly young children
Click to add text
Andenovirus
Andenovirus affect mostly young children
Targets intestines
Targets Urine Tract
Targets Eyes
Targets Respiratory System
Samuel Quinn

8. Adenovirus An example is sore throat Challenging time talking
Painful when swallowing
Can affect anyone
Drink hot drinks
Samuel Quinn

9. Retrovirus caused by reverse transcriptasez
Retrovirus
 caused by reverse transcriptase
 the opposite of transcription
 RNA is transcripted into DNA 
Samuel Quinn

10. Retrovirus An example of an retrovirus is HIV
Targets the immune system
Can also be called AIDS
One of the symtoms is swollen glands
Immune sytem defends body
Samuel Quinn

11. Lytic Cycle Step 1: Virus attaches to bacteria and inserts DNA into it
Step 2: New viruses are created in the bacteria
Step 3: Viruses lyse out of the bacteria (cell dies)
Step 4: Process repeats
Mason Holmes

12. Lysogenic Cycle Step 1: Virus injects DNA into bacteria
Step 2: Viral DNA joins the bacterial chromosome
Step 3: Host cell copies DNA polymerase
Step 4: The cell splits
Mason Holmes

13. Difference Between lytic cycle and Lysogenic Cycle
Lysogenic cycle involves prophage
Lysogenic cycle involves the splitting of the cell
Lytic cycle is faster
Mason Holmes

14. Similarities Between Lytic Cycle and Lysogenic Cycle
Both cycles have the same outcome
Created by virus injecting DNA into bacteria
Mason Holmes

15. What is a T4 Bacteriophage Made Up Of?
RNA – Surface proteins – Membrane Envelope
DNA in the tail sheath – RNA in Head – Surface proteins
DNA in the Head – Tail sheath – Tail fibers
TEM’s – Viruses - Capsids
Max DeAngelo

16. What is a Virus? A Memory Bound Organelle
Particles are made of proteins and nucleic acids
The Flu
A living particle
Max DeAngelo

17. Which is not a sympton of HIV?
a. Swollen Glands b. Headache c. Trouble Speaking d. Muscle Pain C
Samuel Quinn

18. What does HIV target 
a. Immune System b. Brain c. Heart d. Nasal Passage A
Samuel Quinn

19. What is a Similarity Between the Lytic and Lysogenic Cycle
Both include prophage
Both include the cell splitting
Both have the same outcome
Both take the same amount of time
Mason Holmes

20. What is the First Step of the Lytic Cycle
Viruses reproduce inside the cell
 Virus attaches to bacteria and inserts DNA into it
Cell splits
 Host cell copies DNA polymerase
Mason Holmes
