Multi-copy suppressor screen
... To prove that the cells that grow are transformants and not revertants of the ura3mutation in the recipients, it is necessary to perform a “no DNA control”. This is done by performing a mock transformation procedure on cells, without adding any DNA, and plating them on a YMD-uracil plate. DNA can be ...
