Question
Chapter 17.3, Problem 8LO
Summary Introduction
To explain: The relationship between cancer and change in the gene expression that affects cell development processes.
Introduction: Cancer refers to the abnormal growth of cells in the body, which causes an abnormal increase in the number of cells. This prevents the differentiation and growth of the organs. The genes regulating the activity of cancer cells are called oncogenes.

Explain in detail two different genetic mutations that can promote the development of cancer. Include the name (or type) of gene mutated and whether the expression of the gene is upregulated or downregulated. Provide a description of the role the gene plays in regulating the cell cycle and how the cell is affected when the gene no longer produces a functional protein
Explain the molecular mechanisms of cancers caused by a P53 gene mutation.
examine the process of gene expression. Include the following: Explain the regulation of gene expression in eukaryotic cells. Discuss mechanisms by which gene expression may be altered. How do these alterations induce cancer-causing mutations in cell DNA? Explain how cancer is formed. Describe genetic changes found in cancer cells and how these changes lead to alterations in cell behavior. Determine whether proteome data can be utilized in genetic disorder diagnosis. Relate the Human Genome Project data to the analysis of cancer genes. Relates the Human Genome Project's utility in pharmacogenomics and personalized medicine to diagnose and treat cancer
