You’ve learned how biotechnology can be used to make medicines, but biotechnology can also diagnose, predict, and even prevent human diseases. In this module you will test your own DNA to predict whether you can taste a particular bitter compound. The ability to taste this bitter compound isn’t medically relevant, but it will show you how easy it is to determine things from DNA.

### Objectives

In this module you’ll

- Perform a single nucleotide polymorphism experiment and gel electrophoresis.
- Test a hypothesis based on the results of gel electrophoresis.
- Describe how the single nucleotide polymorphism experiment models biotechnology diagnostics.
- Research the cost of a biotechnology diagnostic test.
- Evaluate the availability of a biotechnology diagnostic test to individuals in developed and underdeveloped nations.
