Lytic Cycle

1) In the lytic cycle, what does the bacteriophage attach to on the host cell membrane?
2) After the virus attaches to the host cell membrane what is injected into the host cell?
3) What is another way a virus can enter a cell?
4) The viral DNA/RNA contains instructions for the cell to do what?
5) What can happen to the cell membrane after making many copies of the virus?
6) What do the viruses do once they leave the host cell?

Lysogenic Cycle
7) What happens to the host bacteria’s DNA after the bacteriophage injects its DNA/RNA into the cell?
8) The bacteria pass this “combined” DNA onto daughter cells. The bacteria continue to reproduce and finally enter the lytic cycle when this happens.
9) Once the bacteria are “activated” they begin producing
