Bacteria and Virus Evidence 3: Virus Life Cycles

What is the biggest threat a virus has on a cell?

• The virus will burst of kill the cell
• viral fluid will get into your bloodstream
• The virus will invade your cell but not harm it
• viruses are not a threat to your cell

When a virus invades a living cell, its _______
takes over the cell's functions.

• outer coat
• genetic material
• core
• cytoplasm

Which of the following occurs after a virus attaches to a host cell in the viral reproduction process?

• The host cell dies
• The virus dies
• The virus inserts its genetic information into the host cell
• copies of the virus are immediately released from the host

What is the 1st step of virus infection?

• Entry
• Attachment
• Replication
• Assembly

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

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

A _____________________ infection involves the virus DNA combining its DNA with the host cells DNA. Then hiding for years.

• lysogenic
• lytic
• vaccine
• vinerial

HIV is an example of which type of virus?

• Naked virus
• Bacterial
• Lytic
• Retrovirus

What happens in the lytic cyle?

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus sleeps inside of the host cell
• Virus stay dormant for a long time

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation
