A single copy can trigger cell division, causing tumor formation. d) Cancer‑causing mutations cause both copies of a tumor suppressor gene to become constitutively activated. e)Tumor suppressor proteins are upstream in the cell cycle regulation pathway, whereas oncoproteins regulate more important control points downstream in the pathway.

Question: Cancer is the abnormal growth of cells caused by uncontrolled cell division. Tumor suppressor genes are genes that encode protein products whose normal function is to protect cells from becoming cancerous. When a loss-of-function mutation occurs in a tumor suppressor gene, a cell may progress to a cancerous state.

A man inherited a chromosome with a deletion that removes a tumor-suppressor gene. The protein encoded by this gene normally functions in DNA damage repair.
