Question

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 proto-oncogene. an oncogene. a proto-tumor suppressor gene. a gain-of-function mutation. a tumor suppressor.

Answer 1

a proto-oncogene.

Step-by-step explanation:

The protooncogenes are genes capable of causing cancer when they are activated to oncogenes by mutations that dysregulate their functions. In this case, the mutation in the Ras is a GTP-binding protein convert it to an oncogene that stimulates the cell proliferation mechanism
