Virus Reproduction

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

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

The lysing of a cell occurs in which phase?

• 1
• 2
• 4
• 5

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

HIV is an example of which type of virus?

• Lysogenic
• Bacterial
• Lytic
• None of the above

What happens in the lysogenic cycle? 

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
• Bacteria injects DNA into a host cell

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.

Influenza infects a cell and causes it to lyse immediately. Which type of virus is influenza?

• Lytic
• Lysogenic
• Bacterial
• None of the above
