Genome 4th Entry

"Death"
Ridley explains to the reader that death is caused by the abnormal function of the gene TP53. The gene TP53 has the power to control the production of cells, but if it becomes or is unable to function normally, it would lead to the buildup of large groups of compacted cells called tumors. The tumors build up until it could no longer hold the stress so some may deposit into the blood stream. Once in the blood stream the cancerous blob of cells take root else where in the body and the out of control TP53 continues to make more cells. These tumors sometimes black passage ways and can damage or kill tissues, not only that but it could also be visible on the outside if the tumor is grown large enough, or close to the skin. If the tumor is left untreated, death would occur for sure.
