Viruses are...

• prokaryotic

What does a virus do once it's inside one of your cells?

• It eats up all of the machinery in the cell.

• It uses the cell´s organelles to make copies of itself.

• It prevents the mitochondria from converting glucose to ATP.

What would happen to a virus if it couldn't find a host cell to invade?

• It wouldn´t be able to multiply.

• It wouldn´t be able to travel through the air.

• Its genetic information would wither away.

• It would not be able to exist.

What do viruses have in common with living cells? They both...
