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
