Loss of p53 function occurs in the majority of human tumors. Name two ways in which loss of p53 function contributes to a malignant phenotype. Explain how benzo(a) pyrene can cause loss of p53 function.

D) The level of carbon dioxide increases with the level of available oxygen. 60) The TP53 gene provides instructions for making a protein called tumor protein p53. Known as the guardian of the genome, this protein acts as a tumor suppressor, which means that it regulates cell division by keeping cells from growing and dividing too fast or in an uncontrolled way. The p53 protein is located in the nucleus of cells throughout the body, where it attaches directly to DNA and plays a critical role in determining whether the DNA will be repaired or the damaged cell will self- destruct (undergo apoptosis). If the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be repaired, this protein prevents the cell from dividing and signals it to undergo apoptosis. eg Suppose chromosomes in a skin cell are damaged by ultraviolet radiation. If the damaged genes do not affect p53, which choice correctly predict if the cell will become cancerous and why? No, the cell will…
