    The Science Behind the ACTN3 Polymorphism
    A common polymorphism in the alpha-actinin-3 (ACTN3) gene results in the lack of ACTN3 protein expression in fast twitch muscle fibers in ~16% of the human population (1). This genetic change has been linked with muscle performance in humans (2)...

    Predicting and classifying effects of insertion and deletion mutations on protein coding regions
    Mutations in genes can affect the encoded proteins in multiple ways, and some of these effects are counterintuitive. As for any other knowledge, students must create their own deep understanding of the Central Dogma. Students may not develop this...
