Mitotic segregation of three 2 μm-pBR322 chimaeric plasmids (YEp6, YEp21, and YEp24) was studied in yeast. Each displayed a characteristic rate of loss: YEp6 was lost at approximately twice the rate of YEp21 and YEp24. The loss rates were not significantly increased when two chimaeric plasmids were coresident, nor was the endogenous 2 μm plasmid itself displaced. Therefore these plasmids appear to be compatible in yeast.
