Living World Part 1

Needs host cell to reproduce.

• Virus
• Bacteria
• Fungus
• Protozoan

What happens in the lytic cyle?

• Virus goes in and leaves the host cell

• Virus uses cell to make multiple copies of the virus until the cell lyses

• Virus sleeps inside of the host cell

• Virus stay dormant for a long time

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 the lytic and lysogenic cycle have in common?

• 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 shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

What does a virus have on the outside?

• a protein coat
• a fur coat
• crispy skin
• membrane

What does a virus have on the inside?

• DNA, but never RNA
• RNA but never DNA
• DNA or RNA
• neither DNA or RNA

What is gene therapy?

• when the virus acts as a messenger to carry DNA to a diseased cell.
• When a gene talks about its youth.
• Who's Gene?
• none of the above.

What is a vaccine?

• a girl's name.

• something that helps the body fight infections by using the bodies natural defenses.
