[Abstract] [Article]
Experimental results: Inviable.
Comments: This is unpublished results from Dr. Cross's lab. The mutant is inviable for other unknown causes.

His observation: "Although the mutant is ultimately inviable or extremely slow-growing on galactose, this is not associated with any obvious problems in a short-term experiment. These cells clearly go through several doublings, probably without much difficulty, on galactose medium, and they remain reasonably viable when returned to glucose, like GAL-CLB5 cells. The DNA profile looks like that of GAL-CLB5 controls, mostly 2C DNA. So I think at the level of a computational model, it is not reasonable to expect the model to predict inviability of GAL-CLB5 cdh1∆ mutants. They should probably look pretty viable".
