WebJun 6, 2024 · When proto-oncogenes are mutated or increased in numbers (amplification) due to DNA damage (such as exposure to carcinogens), the proteins produced by these genes can affect the growth, proliferation, and survival of the cell, and potentially result in the formation of a malignant tumor. 2 Web(Hint: How does mutation affect genetic variation?) Mutations increase genetic variation, which is needed for natural selection to bring about evolutionary change. Describe how natural selection can affect traits controlled by single genes. It can lead to changes in allele frequencies and the evolution of traits.
