Oncogenesis is one name for the process where normal cells turn into what?

• Correct Answer: cancer cells
• blood cells
• lung cells
• brain cells

Explanation: Carcinogenesis is the process by which normal cells are transformed into cancer cells. The process is also known as oncogenesis or tumorigenesis and it depends on both the activation of oncogenes and deactivation of tumor suppressor genes . Proto-oncogenes, the non-cancerous normal version of an oncogene, can be a transcription factor like c-fos, c-jun and c-myc, or a gene whose product is involved in signal transduction, leading to altered gene expression. When mutations cause the regulation of this process to be disturbed, cell proliferation can be enhanced leading to tumorigenesis.
