A mutation in a gene can sometimes result in uncontrollable cell division. This is a feature characteristic of most cancerous cells. What organelle would be important is controlling this function?

I can't find the answer anywhere! :oops:

Thanks!

Well lysosomes would "regulate" any cancerous cells by releasing digestive enzymes to cause apoptosis in the tumorous cell, but specifically speaking, it's the p53 gene's control that determines whether or not a cell is uncontrollably dividing.

You can say that the nucleus itself is a "first barrier" to cancer and the lysosomal reaction is a "second barrier". If these two fail (obviously there are more mechanisms but these two are the most significant) then you've got yourself a tumor.
