Upon DNA damage or other stresses, various pathways will lead to the dissociation of the p53 and mdm2 complex. Once activated, p53 will induce a cell cycle arrest to allow either repair and survival of the cell or apoptosis to discard the damaged cell. The p53 protein plays a very important role in cell division. It has the ability to stop cell dividing when there is damaged DNA, preventing multiple cells to have damaged DNA after cell dividing. A cell might need to stop dividing in order to stop the spread of the damaged DNA. 6. Why was gamma radiation used in this experiment?

Rb, p53, and p21 act primarily at the G 1 checkpoint. p53 is a multi-functional protein that has a major impact on the commitment of a cell to division because it acts when there is damaged DNA in cells that are undergoing the preparatory processes during G 1. If damaged DNA is detected, p53 halts the cell cycle and recruits enzymes to repair ... Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. This question is an application of Learning Objectives 3.7 and Science Practice 7.4 because the students are predicting how a change in regulation of the cell cycle can result in cancer. Answer. The role of normal p53 is to monitor DNA for damage. If damage is detected, p53 triggers repair mechanisms. If a cell is stressed, p53 normally functions to shut down cell division. What activates p53 and what, in turn, does p53 do (slide 3)? Low oxygen concentration, DNA damage, Chemotherapeutic agents, as well as other stress can activate p53. In turn, p53 activates genes that stop cell growth or even trigger the cell to die.If the answer is "yes," the cell grows and divides Virtual Lab: The Cell Cycle and Cancer Worksheet Go to: Purpose: In this investigation you will explore the similarities and differences between the cell cycles of normal cells and cancer cells DNA repair genes Most likely you have knowledge that, people have look numerous time for their favorite books taking into consideration this ...1 Chromosomes) The Results for Biointeractive The Eukaryotic Cell Cycle And Cancer Answer Key The cell cycle is a four-stage process in which the cell increases in size, copies its DNA, prepares to divide, and divides Thus, cancer and cell cycle Leukemia and a Magic Bullet (pg 12) - [NOTES handout] Leukemia and a Magic Bullet (pg 12) - [NOTES ...Worksheets are provided.
