Verified step by step guidance

Understand the role of Protein X: It stops cells from growing and dividing, which is a key function in preventing uncontrolled cell proliferation.

Identify the type of gene associated with stopping cell growth: Genes that inhibit cell division and prevent tumor formation are known as tumor-suppressor genes.

Differentiate between oncogenes and tumor-suppressor genes: Oncogenes promote cell division and can lead to cancer if mutated, whereas tumor-suppressor genes inhibit cell division.

Consider the function of other gene types: Protein kinase genes are involved in signaling pathways, proto-oncogenes are precursors to oncogenes, and protein vesicle genes are related to transport within cells.

Conclude that the gene coding for Protein X, which stops cell growth, is a tumor-suppressor gene, as it aligns with the function of inhibiting cell division.
