You isolate a new cdc mutant in budding yeast and call it cdc104.

Now you reverse the order of the treatment, you arrest cells for 2 hours in S phase by adding hydroxyurea. Then you wash out the hydroxyurea but grow the cells at 37°C. Now the cells undergo one round of division before arresting. 6.In what phase of the cell cycle does the cdc104 mutant arrest?7. What mammalian cyclin functions at the same point?
