WebUnstable cells might have a slower rate of clonal expansion than stable cells because of an increased probability of generating lethal mutations or inducing apoptosis. We show that the different growth rates of genetically stable and unstable cells during clonal expansion represent, in general, only a small disadvantage for genetic instability. front porch welcome matsWebEach genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.
