Question

Quizplus · Accepted Answer

Oncogenes are mutated forms of normal genes known as proto-oncogenes that promote cell proliferation and survival. These mutations act dominantly and can lead to the development of cancer. Polymerases are enzymes involved in DNA replication, activators are proteins that stimulate gene expression, and tumor suppressors are genes that inhibit cell growth and division.
