Viral Structure

What part of the virus is number 3?

• Capsid

• DNA

• Projections

• Envelope

Some viruses have envelopes made of cell membranes. Where did they get those membranes?

• It is coded in their DNA.

• From the host cell.

• From the protein capsid

• They make it during mitosis.

Viruses are...

• prokaryotic

• eukaryotic

• non-living

• endospores

How does a virus cause a person to develop the common cold?

• invades the host cell to reproduce

• removes energy from the host cell

• produces toxins in the host cell

• protects the host cell from bacteria
