Experimental results: Wasch, Fig. 2. It has similar phenotype as sic1∆ cdh1∆ being semi-lethal on glucose medium. Mutant cell arrests with replicated but un-separated DNA without long mitotic spindle. It showa a high rate of loss for plasmids containing single replication origin, but the rate of loss is significantly decreased for multi-origin plasmids. This indicates that the mutant is not blocked from mitotic exit, but it has problems with origin usage.
Comments: In simulation, the mutant is able to exit the first mitosis, but dies because of DNA replication problem. [ORI] (grey line) is not re-licensed after the first mitosis.
