Verified step by step guidance

Understand the role of tumor suppressor genes: Tumor suppressor genes are responsible for regulating cell growth and ensuring that cells do not divide uncontrollably. They act as a brake on cell proliferation.

Recognize the effect of mutations in tumor suppressor genes: When these genes are mutated, they often lose their function, leading to a lack of control over cell division. This can result in increased cell proliferation, contributing to cancer development.

Differentiate between tumor suppressor genes and oncogenes: Oncogenes are mutated forms of genes that normally promote cell growth. When mutated, they become overactive, leading to excessive cell division. In contrast, tumor suppressor genes, when mutated, lose their ability to inhibit cell growth.

Clarify the statement: The statement claims that tumor suppressor mutations result in higher amounts of gene activity. This is incorrect because mutations in tumor suppressor genes typically lead to a loss of function, not an increase in activity.

Conclude with the correct understanding: The correct answer to the statement is 'False' because tumor suppressor mutations generally result in decreased gene activity, leading to uncontrolled cell growth, not increased gene activity.
