Virus Structure

Viruses cannot

• be crystallized
• live in bacteria
• reproduce on their own

_________ are found in BOTH viruses and in all living organisms. 

• Genetic Material 
• A cell membrane
• ribosomes

The projections on the virus (tail fibers) are used for - 

• carrying genetic material 
• attaching to a host cell
• protecting the DNA

Virus needs to attack a host cell in order to survive because 

• they lack DNA so they must use the DNA of the host cell
• they cannot reproduce on their own therefore they hijack cell's machinery 

HIV weakens the immune system by killing 

• antibiodies
• immune cells
• skin cells
