Question

Quizplus · Accepted Answer

Proto-oncogenes are genes that regulate cell division and growth. When these genes are mutated or activated, they can become oncogenes and promote uncontrolled cell division, leading to cancer. In the case of skin cells, proto-oncogenes may be responsible for promoting cell division and allowing the cells to move past the G1 checkpoint.
