Genome 6th Death

In the chapter of this book, this chapter centralizes on cancer, which may cause and lead to death. Cancer is known as the reproducing of cells when they are not needed to and produced excess cells. A gene in which is called tp53 acts as a suppressor for the rogue cancer cells. The tp53 is located on chromosome 17 and suppress tumor producing cells. The genes help encourage cell growth and therefore cancer is caused when they are kept on working. As time progresses, a person with a tumor gets into more danger as their cells are constantly dividing, thus more mutations are created. BRCA1 and BRCA2 are both mutator genes that cause breast cancer in many woman. tp53 produces a protein that halts cell division and slows the growth of cancer. A lot of types of tp53 gets mutated very early and many medical treatment have little effect. Chemotherapy and radiation therapy do not always work very effectively in the later stages of their diseases.
