Markers and Kill Switches

Dual selection system (aka killswitch) ideas

• use selectable markers such as URA3 to control whether an integration plasmid is replicated or not
  
• cells with the URA3 gene can grow on media without uracil, but get killed by 5-Fluoroorotic acid (5-FOA)
  
• cells without the URA3 gene die on media without uracil, but can survive exposure to 5-FOA
