Viruses

How do viruses reproduce?

• They copy their own genetic material inside a protein coat.
• They kill a cell and reproduce inside it.
• They invade a living cell and use the cell's functions to replicate their genetic material.
• They do not reproduce because they are not technically living things.

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.

Viruses are exceptions to the cell theory, but they have some characteristics of living things. What is one of these characteristics?

• they contain chlorophyll
• they reproduce by mitosis
• they contain genetic material
• they are made up of many specialized cells

The lytic cycle takes the longest out of the two viral reproductive cycles. 

• True
• False

What process is this?

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

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

What is the first step to both viral cycles?

• The virus attaches to a host

• the virus injects genetic material

• the host gets sick

• the cell is destroyed

Viruses are considered

• living things

• non-living things

• partially living things

viruses are non-living because

• they cannot reproduce on their own

• they do not evolve

• they have no DNA

• they cannot be destroyed

What part of a virus houses the genetic material (DNA/RNA)?

• tail

• nucleus

• capsid

• lipid
