3.  Lytic Cycle- results in lysis (breaking open) of host cell ◦ The virus turns the cell into a virus-producing factory  Lysogenic Cycle- Viral DNA is replicated w/o the death of the host cell or phage production ◦ Phage becomes a prophage ◦ Prophage- DNA of a phage that is inserted by genetic recombination into the DNA of a prokaryotic chromosome

6.  Viruses affect both plants and animals ◦ Viral infections that infect animal cells  Colds, flu, small pox, polio, chicken pox, etc, ◦ Viral infections that infect plant cells stunt plant growth and lowers that amount of crops farmers have to sell
