Cancer
Cancer is a very complex disease having many causes.
What are some of these causes of cancer?
Although tobacco smoking is responsible for a large number of human cancers, not all smokers develop cancer. Why is this?
Pick a specific tumor suppressor gene or oncogene and explain how this gene can lead to or prevent cancer. Be sure to focus on the mechanism of how your chosen gene impacts the cell cycle. You can alternatively pick a virus that has been associated with cancer and explain how that virus impacts the cell cycle and ultimately leads to cancer.
