Answer: Ras activity would be significantly slower in its response to extracellular signals.
Explanation:
• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)
• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase
• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)
