1. Which organelles is the main calcium store for signaling? Lyosome; ER; Golgi; secretary vesicles 2. A temperature sensitive mutant yeast strains/stops dividing when shifted from. 25 degrees Celsius to 37 degrees Celsius. These cells are analyzed at different temperatures by a machine that measures the amount of DNA they contain. What would explain the behavior of the mutant? Anaphase promoting complex is inactivatend; s cdk is inactivated; m cdk is inactivate; m cycling is overexposed 3.which of the following statements about proto oncogenes is true? Proto oncogenes inhibit cell growth and division; cancer cells often contain loss of function mutations in proto oncogenes; proto oncogenes are needed for cells in normal tissues; none

Gene amplification of a tumor suppressor gene is more dangerous than gene amplification of a proto oncogenes; tumor suppressor genes are more highly expressed in cancer cells than normal; some tumor suppressor inhibit cell cycle progression in normal cells; individuals with only one functional copy of a tumor suppressor gene have the same risk of developing cancer as individuals with two functional copies of a tumor suppressor gene
