Practice Question

Which of the following is true regarding the role of oncogenes in cancer development?

Answer Choices:

Correct Answer:

Genes that regulate cell division can become oncogenes when mutated

Rationale:

🧬Oncogenes arise from proto-oncogenes, which normally help regulate cell growth and division.

⚠️When these genes become mutated or overexpressed, they may lose regulation and promote uncontrolled cell proliferation.

🦠These mutations are implicated in many cancers, as the resulting proteins may override normal cellular checkpoints.

🔍Oncogenes are a key factor in tumor formation because they drive excessive and abnormal cell division.

📌Core Message

Oncogenes are mutated regulatory genes that drive uncontrolled cell division and contribute to cancer development.
