In order to answer this question, let's talk about cancer.
00:04
Which of the following events is unlikely to be associated with cancer? so remember that you have normally in your cells, you have proton cogens.
00:16
Proton cogens.
00:17
And these proton cogings are going to produce proteins that are going to lead to cell proliferation.
00:25
Cell proliferation, okay? when there is a mutation in proton cogens, they are going to become oncocon genes, and they are going to cause uncontrolled cell proliferation.
00:42
Now, in order for these proton co -gings not to get out of control, you have tumor suppressor genes, and these tumor suppressor genes are going to are going to regulate these proton co -greens in order for them not to become out of control.
01:05
If you get a loss of function mutation in a tumor suppressor gene, then even when your proton cogens are normal, then your tumor suppressor genes are normal, then your tumor suppressor genes are not going to be able to regulate your proton cogens and you're going to have like excessive cell proliferation.
01:19
So in this question it says, which one of the following events is unlikely to be associated with cancer? option a says a mutation of a cellular proton co -gene in a normal d+ + cell and this is true because if you get a gain of function of a proton co -gene, your proton co -gene is going to gain function.
01:37
So even when your tumor supercell genes are normal, they are not going to be able to control this proton co -gene...
