What concrete is to civil engineers, DNA is to biological engineers. At first glance, DNA might seem like any other material, a building block, like concrete. A material that, over time, humans learnt to refine, assemble, and optimize into products with specific functions. This analogy, brought to us by our guest blogger, MRes student Emile Durand, captures the essence of biological engineering’s approach. But to fully understand the potential of this topic, we must first learn what makes DNA different from other building blocks!Â
