Ras is a GTP-binding protein that is often defective in cancer cells.A common mutation found in cancer cells causes Ras to behave as though it were bound to GTP all the time, which will cause cells to divide inappropriately.From this description, the normal Ras gene is a/an

The normal Ras gene is a proto-oncogene because it has the potential to cause cancer when mutated or overexpressed in a way that leads to its constant activation, as described in the scenario. Proto-oncogenes normally regulate cell growth and division, but when they are mutated, they can become oncogenes that drive cancer progression.
