Which of these accurately describes tumor suppressors and proto -oncogenes? a, if you have both, you will always develop cancer.
00:11
B, when a proto -oncogen mutates, it becomes a tumor suppressor.
00:15
C, both prevent the spread of cancer by targeting and destroying cancer cells.
00:20
Or d, proto -oncogenes, co -growth factors, tumor suppressors inhibit cell division of damaged cells.
00:26
Here's this one is d.
00:28
So these are both types of genes that are involved in cancer development, and how it works is a proto -oncogene.
00:37
If mutated, becomes an oncogene.
00:41
And for this, it's always on.
00:44
Whereas a tumour suppressor is a risk if turned off.
00:51
So proto -oncocines code for growth factors, because if they are always on, then they're they are always encouraging growth...
