Are you suffering with 10th grade biology? Do you want to inspire a student to think about genetics? This site allows a participant to be a doctor in outer space. By examining patients, determining treatment, and carrying out gene therapy, the learner gains a depth of understanding of genetics. Be advised this looks cute but it is a pleasant disguise for high-level genetics learning. Do not enter the site thinking you will "just play around for a few minutes," you will find yourself researching and engaged for more than a "few minutes."
