2. Are mutations always deleterious?Give an example of a mutation that has either no ill effect or perhaps a useful one.
3. What are transposons? How might they be related to mutation?

Part Two: Due Thursday by 6pm
a recommendation (at least two paragraphs long) for a promising treatment of the genetic disease you selected. The recommendation should include:
- A brief description of the genetic disease and how it occurs
- An explanation of the treatment you selected
- Reasons why this treatment is particularly promising
- References to at least two sources outside of the Required Resources
- All references cited in APA format
Read a selection of your colleagues’ postings.
To prepare for this Discussion:
- Review Chapter 6 “Cancer” in the course text and consider the following:
- What a mutation is
- The causes and effects of particular mutations
- Review Chapter 9, “Genetically Modified Organisms,” focusing on how genetic mutations occur and ways genetic modification is being considered in the treatment of genetic disorders.
- Conduct research to learn more about human genetic diseases. Identify one that particularly interests you. Learn more about the disease and how it is being treated, as well as treatments under development. Compare and contrast the treatments you read about to identify one that you find particularly promising.
- Explore the Internet, especially websites that contain news and articles about genetic diseases and their treatment. This week’s Optional Resources suggest websites where you could start your search.
