Epidemics 2

What process is this?

• phagocytosis
• lytic cycle
• lysogenic cycle
• formation of antibodies

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

This virus attacks the white blood cells (immune cells) of the human body. Eventually, the immune system cannot handle the viral invasion. This makes the body prone to attack from other viruses and bacteria. What is the name of this infectious viral disease?

• AIDS
• Cancer
• Diabetes

This infectious viral disease has many symptoms, from chills, fever, and aching muscles to coughing and sneezing to nausea and vomiting. The symptoms show up within 2-7 days after the cell is infected.  This is an example of?

• Lytic Cycle
• Lysogenic Cycle
• Meiosis

Symptoms of HIV do not show up immediately because the virus can 

• stay dormant for years
• mutate quickly 
• stay outside the cell for a long time

What is the difference between the lytic and lysogenic virus reproductive cycles?

• lysogenic is longer
• they are the same
• Lytic is longer
• Both are different each time

What is one way that a lysogenic infection differs from a lytic infection?

• A lysogenic virus does not act on bacteria as a lytic virus does.
• A lysogenic virus can remain in the host DNA for a longer period without becoming active.
• A lysogenic virus contains RNA instead of DNA.
• A lysogenic virus directs the production of new viruses right away.

A _____________________ infection involves the phage combining its DNA with the host cells DNA. Often hiding for years.

• lysogenic
• lytic
• vaccine
• vinerial

HIV is an example of which type of virus?

• Naked virus
• Bacterial
• Lytic
• Retrovirus

What is the 1st step of virus infection?

• Entry
• Attachment
• Replication
• Assembly
