About 5 % of our cells is built with RNAs - tiny molecular machines performing all sorts of tasks, from coding and decoding to maintenance. Only recently most of us got a little extra boost of them, through COVID-19 vaccine. Even more excitingly, those same tiny molecules are thought to hold an answer to where and how life came from on Earth about 4 billion years ago. And why it looks the way it does. But how can study them? Computer Simulations come to our rescue.
