In this PNAS podcast, the concept of the relatively new "gene drive" biotechnology application is discussed, particularly as it applies to the potential to impact control of malarial vectors in wild populations. The mechanistic nature of the procedure is discussed, as are social considerations for future use of this technique.
This activity utilizes the emergence of antibiotic resistance, and mechanisms thereof, to teach essential concepts including natural selection, bacterial gene transfer, mutation, and gene expression. It also provides a connection between course content and modern applications of important concepts. The activity (app. 25 minutes) is intended for introductory students in biology. It is flexible and...
