WebThe Eukaryotic Cell Cycle and Cancer – Overview a) To cause cancer, proto-oncogenes require one allele(s) to be mutated and therefore are considered dominant. The mutation results in a gain_ of function. Normally, tumor suppressor genes inhibit the cell cycle. How do mutated tumor suppressor genes affect the cell cycle? WebHowever, when they become mutated, they can cause cells to divide and grow in an uncontrolled way, leading to the formation of a tumor. Oncogenes can affect the cell cycle by causing cells to divide and grow uncontrollably, leading to the formation of a tumor. They can also interfere with the normal processes that stop cell growth and division ...
