Question
Chapter 16.3, Problem 1CC
Summary Introduction
To discuss:
How mutation in protein coding genes functioning in apoptosis can lead to cancer.
Introduction:
Apoptosis is defined as the programmed cell death (PCD). It is a process, which only occurs in multi-cellular organisms. The cells undergoing PCD include blebbing, fragmentation of DNA (deoxyribonucleic acid), cell shrinkage, and engulfment by the phagocytes.

D)
The level of carbon dioxide increases with the level of available oxygen.
60)
The TPS3 gene provides instructions for making a protein called tumor protein p53. Known as the guardlan of the genome,
this protein acts as a tumor suppressor, which means that it regulates cell division by keeping cells from growing and dividing
t0o 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.
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 not…

- Describe the general process of cell signalling pathways: what events take place for a signal to cause cellular changes? Provide examples and how perturbation of these events can result in “cancer pathways”. In addition, describe in detail a typical cancer pathway and its strategy to activate gene expression. What is the origin of many cancer pathways, i.e., during which stage of an organism’s live process(es) are they physiologically activated? Why is this important for cancer development?arrow_forwardTumor suppressor proteins can assist in slowing down the cell cycle under appropriate conditions. In humans, the TP53 gene encodes a tumor suppressor called p53. Most mutations in the TP53 gene result in a mutant form of p53 that can no longer function to slow down the cell cycle, which can lead to a cell becoming cancerous. However, some mutant forms of p53 actually possess the ability to increase a cell's resistance to anticancer treatments. Which of the following BEST describes the latter type of mutation? loss-of-function mutation gain-of-function mutation suppressor mutation reverse mutationarrow_forwardDescribe the effects of the mutation causing the p21 promoter to no longer bind p53 on cell signaling pathways and metabolism or cell cycle control.arrow_forward
