The daughter cells generated by the subsequent mitoses
Suppose you have a human tissue culture line in which both normal copies of the gene coding for the Mad2 protein have been replaced by mutant gene copies, each of which contains the same temperature-sensitive mutation. The resulting mutant Mad2 protein folds and functions normally when the cells are maintained at 22°C, but the protein […]
