And that's because RNA and proteins consist of two different languages. The language used by RNA are these nucleotides. But the language used by the proteins are amino acids. And nucleotides and amino acids are two completely different types of molecules. So the question is, in the process of translation, how do the ribosomes actually know to basically create that specific sequence of amino acids if the RNA consists of these different molecules we call nucleotides? Well, the ribosomes of the cell basically use a system called the genetic code.
