What roles do genes and mutations play in cancer formation?
Hi I'm doing an essay and i feel this is an essential question to answer in it so ive done some research but would like some more specificly answering the question. Thank You!
What role does mitosis play in cancer formation?
It is part of cell division (in cancer cells as well as normal cells). A bit simplified you can say: No mitosis - no cancer formation. No mitosis - no renewal of normal cells.
How is cancer formed?
Cancer is a mutation of cells. Healthy cells are replaced with cells that do not function. For instance, with lung cancer, the cancerous cells are not able to move oxygen. The cells take up space, and resources (like nutrition), but they perform no function.
How can aberrations in the cell cycle lead to tumor formation?
Simple answer: The cell cycle is divided up into separate phases (S, G0, G1, M); each point of transition from one phase to another (a checkpoint) is governed by multiple proteins which serve as either "accelerators" or "brakes" for the cell cycle. These proteins are coded by chromosomes (DNA), and it is the mutation in the protein-specific DNA which creates either no protein, overactive protein, or underactive protein. IN any case, it creates a disruption to the cycle, which disturbs orderly cell growth and division. This can lead to cancer.

Questions about Cancer and also Split ends?
NOTE: if you are asking what cancer a i mean (cancer cancer..?) #1. is the common age to get cancer? #2. What are the symptoms of cancer? Truth or False Questions: #3 Is it true that having spile ends is a sign of cancer? [from a friend.. which she heard from a rumor too] --- becuase just yesterday and today i found my first few split ends and than i cut them and found some today. #4 Is it true that if you have a lot of bruises means you have cancer? [heard from a friend.. but she is not sure] Should I? or Should I Not, Questions (cancer and about split ends) #5. Should i cut my splite ends myself or should i go to the barber and tell her to cut 2 1/2 or 4 inches of my hair (cus its starting to get long and plus the split ends and also that its hard to wash and dry my hair)
