Virus/Organisms/Cell Organelles

A virus consists of:

• RNA or DNA and a cell membrane

• RNA or DNA and a protein coat

• RNA and DNA and a protein coat

What happens after the virus has been taken up by the cell?

• it begins making protein

• it divides, or replicates

• it inserts into the host DNA

• it switches to infectious mode

What does the lytic cycle result in?

• destruction of the infected cell and the membrane

• multiple new cells

• people going in sane
