Total questions: 15
Worksheet time: 10mins
What is the sole purpose of a virus
Invade and control cells making them replicate more viruses
Lyse bacteria
Force cells to give up water and shrink
Which of the following is false about the structure of a virus?
Projections on the surface of the virus allow it to attach to cells
Center of the virus contains genetic material such as RNA or DNA
Surrounding the genetic material is a protein capsid layer
Flagella on the virus allow it to locomote
Which of the following images are viruses? (There is more than one answer choice.)
Which would you take to help with a viral infection?
antiviral medication
antibiotic medication
antihistamine medication
Vitamin E supplements
How does Antiviral medication help with viral infections?
Antivirals do not allow the virus to attach to cells or reproduce inside cells
Antivirals destroy the cell wall of viruses
Antivirals hack into viruses corrupting their DNA
Why do viruses have projections on the outside?
To send signals to other viruses.
To maintain their structure.
To attach to the host cell.
To reproduce.
Which occurs during the lysogenic cycle of a viral infection?
Viral genes instruct the host cell to make more vial protein capsids and enzymes needed for viral replication
The virus takes over the cell, makes copies of itself, and usually kills the host cell.
The virus produces active, immediate infections
The viral genes becomes a part of the host cell DNA, so they cell continually makes more copies of the virus.
Animal viruses often infect only specific host cells because
they must have the same DNA as the host cell
viruses have receptors for the host cells glycoproteins (keys)
the host cell has specific receptors for the glycoproteins (keys) of the virus.
the enzymes of the virus can attach only to specific host cells
The instructions for making new copies of a virus are
a part of a virus's capsid
coded in either RNA or DNA
coded in surface proteins attached to the protein coat
found only in bacteriophages.

Viruses are larger than bacteria?
True
False
