Now let's suppose the gene is a normal gene and that means this will be a normal protein. But what happens if that gene that encodes for this structure is actually mutated in some way? And let's suppose we mutate that gene in such a way so that this molecule loses its ability to basically hydrolyze the GTP back into GDP. And so if there's a mutation that takes place in the Ras gene, and the mutation basically destroys the Gtpa's activity of this g protein, then once the protein is activated, it will remain in the on position. It will remain active. And that means it will continually stimulate these processes.
