CorrectIncorrect - Question 6 of 14
6. Question
Put the steps of the virus reproduction process in correct order.
- New bacteriophage particles are assembled.
- The cell lyses, releasing the newly made bacteriophages.
- Bacteriophage (Virus) attaches to the surface of the host.
- Bacteriophage DNA replicates and phage proteins are made.
- The viral DNA enters the host cell.

7. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
- This infection can stay in the body for years before becoming active…
CorrectIncorrect - Question 8 of 14
8. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
- This infection makes copies of its virus, bursts out the host cell, and invades other cells immediately
CorrectIncorrect - Question 9 of 14
9. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
- Examples of this virus are common cold, rabies, AIDS…
CorrectIncorrect - Question 10 of 14
10. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
Examples of this virus are Hepatitis B, HIV
CorrectIncorrect - Question 11 of 14
11. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
- Replicates copies of itself with the host cell DNA without immediately killing the host cell…
CorrectIncorrect - Question 12 of 14
12. Question
Type whether the statement describes a lytic cycle infection, lysogenic cycle infection, or both.
- Injects it’s viral DNA, makes copies of its DNA to make more viruses, leaves the host cell and infects other cells…
CorrectIncorrect - Question 13 of 14
13. Question
Put the steps of the lysogenic cycle infection in order.
- A virus injects it's DNA inside of a host cell where it attaches to and is copied with the host cell DNA without damaging the host cell.
- Lysogenic infection turns into an active lytic infection, bursts from host cell, and infects other cells.
- Environmental factors and certain chemicals trigger the virus to become active. Removes itself from host cell DNA and directs the synthesis of new virus particles.
- Virus DNA may replicate with host DNA for many generations, which infects all of the daughter cells of the original host cell.
