Problem:
Question: Can two plasmids with the same origin of replication (for example pBR322 ori) and thus from the same incompatibility group be successfully co-transformed in E. coli?
Question: What are the mechanisms that would prevent the two plasmids from co-existing together?
Question: Does it matter what is the dual resistance selection?
Question: How would the efficiency of co-transformation compare to the efficiency of a uni-transformation?
