**Understanding Gene X and Its Role in Cell Proliferation****Gene X is responsible for cell proliferation and when gene X is expressed, the cells divide and go through the normal cell cycle. When gene X is not present, proliferation ends.****a) What is a dominant mutation that can occur in gene X that would have a dominant effect on cell proliferation? And where in gene X would the mutation occur (i.e. promoter? etc)?****b) What is a recessive mutation that can occur in gene X that would have a recessive effect on proliferation and where in gene X would the mutation occur?****Explanation:**This handwritten note discusses the role of Gene X in cell proliferation, emphasizing its importance in the normal cell cycle. When Gene X is active, cells divide and proliferate, but in its absence, cell proliferation ceases. Students are prompted to think critically about potential genetic mutations that could affect the function of Gene X:1. **Dominant Mutation:** - A dominant mutation in Gene X might result in continuous cell proliferation even in conditions where normal Gene X would not be active. This could involve mutations in regulatory regions such as the promoter region, leading to constant activation of Gene X.2. **Recessive Mutation:** - Conversely, a recessive mutation might lead to a loss of Gene X function, causing cell proliferation to halt. Such mutations could occur in essential parts of the gene that are crucial for its function, potentially disabling the gene entirely if both alleles are affected. This exercise helps students understand genetic mutations' implications and their specific locations within a gene, enhancing their comprehension of genetic regulation in biological processes.
