ArbitrLikvidat [17]

Answer:

E. They decrease the rate at which Ras hydrolyzes GTP.

Explanation:

Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.
