All viruses are different, but what are two parts that a virus must have?
Genetic Information (DNA or RNA)
a lipid membrane
a nucleus
a protein coat
Which of these statements is true?
A virus is unicellular, it has only one cell.
A virus may sometimes be multicellular, have many cells.
A virus has no cells
Which statement is true?
A virus has a nucleus, but no other organelles.
A virus has a nucleus and ribosomes.
A virus has no organelles, because it has no cells, and it is non-living.
A virus is so small that 250,000 viruses could fit inside
a grain of sand
an apple
a basketball

lipids
proteins
carbohydrates
Which sentence is true
All viruses, although they are not living, have a lipid layer that surrounds them.
Many viruses, although they are not living, have a lipid layer that surrounds them. This includes the corona viruses.

sugar sticks
spike proteins
covid claws
Which sentence is true about this picture.
It shows a virus being made.
It shows a virus entering the cell of a human or animal.
It shows a virus being destroyed by soap.
At the top left of this picture, you can see the spike protein of a virus fitting perfectly into a receptor site on our cells. Which sentence below is true?
Humans have receptor sites for viruses on our cells because we want viruses to invade our cells.
Humans have receptor sites for viruses on our cells because those receptor sites were made for a different purpose, but viruses evolved to be able to use them.
Once the virus is attached to our cell, the lipid layer of our cell and the lipid layer around the virus can merge because
Lipids attract lipids
Lipids attract proteins
The DNA instructs them to do this.
Which sentence is true?
Soap destroys viruses because it dissolves the DNA or RNA
Soap destroys viruses because it bends the spike proteins
Soap destroys viruses because it breaks up the lipid layer and allows it to be washed away.
Soap destroys viruses because it is acidic.
Once a virus gets into a cell, it
Releases its DNA or RNA into the cell.
It begins to create DNA or RNA in the cell.
It destroys its own DNA and RNA in the cell.
