Proteins are some of the most fundamental tools in our cells. In many cases they are not just the metaphorical "bread and butter" of our biochemistry, but also the butter-knife and the hand that holds it. On this episode of gradcast, hosts Nikol Posnov and Connor Chato speak with Josh Isaacson, a researcher of one of the fundamental tools that assembles these proteins: tRNA. Tune in for a talk about this biochemical starting point, and what can go wrong when it doesn't work quite as expected. To find out more about Josh you can follow him on Twitter @JoshIsaacson
