WebSep 4, 2024 · In the case of a cell, the cell keeps dividing out of control, which can lead to cancer. Tumor suppressor genes are genes that normally slow down or stop cell division. When a mutation occurs in a tumor suppressor gene, it can no longer control cell division. This is like a car without brakes. The car can't be slowed or stopped. WebApr 11, 2024 · When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other.
