Question:
Is there a difference between oncogenes and tumorsuppressor genes?
1. Yes, oncogenes are genes that can cause cancer whenthey become mutated to become proto-oncogenes, whereas tumorsuppressor genes play no role in cancer.
2. Yes, oncogenes prevent cancer from forming unlessthey are mutated to become proto-oncogenes, whereas tumorsuppressor genes stimulate the formation of cancer even in theabsence of mutation.
3. No, oncogenes and tumor suppressor genes bothstimulate the development of cancer, even in the absence of theirbecoming mutated.
4. Yes, oncogenes are mutated versions of genes thatpromote abnormal cell division (such as ras), whereas tumorsuppressor genes are genes that normally hold cell division incheck when it is not appropriate .
5. No, since both types of genes contribute to thedevelopment of cancer, there is no difference between them.
which is correct?
