Question

that occur within specific genes that code for proteins that monitor the cell cycle increase the risk for development of cancer.
mutagens
cancers
mutations
oncogenes

Explanation:

Mutations in genes that code for proteins monitoring the cell cycle can disrupt normal cell - cycle regulation. This disruption leads to uncontrolled cell growth, a hallmark of cancer development. Oncogenes are genes that have the potential to cause cancer when mutated or expressed at high levels, but the question specifically refers to changes (mutations) within genes. Mutagens are agents that cause mutations, not the mutations themselves. Cancers are the result of these genetic changes (mutations) rather than the change within the genes.

Answer:

Mutations
